Top 15 Amazing Facts About The Human Body

In our ongoing quest for wonderful facts about all manner of things, we have put together this list (with thanks to the Reader’s Digest Book of Facts), a great list of amazing human facts. These are the fifteen most wonderful things about our bodies that, hopefully, are news to most of our readers! So, onwards:

1

Facts 1 – 5

Compact Spongy Bone

1. The stomach’s digestive acids are strong enough to dissolve zinc. Fortunately for us, the cells in the stomach lining renew so quickly that the acids don’t have time to dissolve it.

2. The lungs contain over 300,000 million capillaries (tiny blood vessels). If they were laid end to end, they would stretch 2400km (1500 miles).

3. A mans testicles manufacture 10 million new sperm cells each day – enough that he could repopulate the entire planet in only 6 months!

4. Human bone is as strong as granite in supporting weight. A block of bone the size of a matchbox can support 9 tonnes – that is four times as much as concrete can support.

5. Each finger and toenail takes six months to grow from base to tip.

2

Facts 6 – 10

Kidney-Anatomy

6. The largest organ in the body is the skin. In an adult man it covers about 1.9m2 (20sq ft). The skin constantly flakes away – in a lifetime each person sheds around 18kg (40 lb) of skin.

7. When you sleep, you grow by about 8mm (0.3in). The next day you shrink back to your former height. The reason is that your cartilage discs are squeezed like sponges by the force of gravity when you stand or sit.

8. The average person in the West eats 50 tonnes of food and drinks 50,000 liters (11,000 gallons) of liquid during his life.

9. Each kidney contains 1 million individual filters. They filter an average of around 1.3 liters (2.2 pints) of blood per minute, and expel up to 1.4 liters (2.5 pints) a day of urine.

10. The focusing muscles of the eyes move around 100,000 times a day. To give your leg muscles the same workout, you would need to walk 80km (50 miles) every day.

Facts 11 – 15

Eyeball2-7Apr07

11. In 30 minutes, the average body gives off enough heat (combined) to bring a half gallon of water to boil.

12. A single human blood cell takes only 60 seconds to make a complete circuit of the body.

13. A foreskin, the size of a postage stamp, from circumcised babies take only 21 days to grow skin that can cover three (3) basketball courts. Amazing isn’t it. Thanks to science. The laboratory-grown skin is used in treating burn patients.

14. The eyes receive approximately 90 percent of all our information, making us basically visual creatures.

15. The female ovaries contain nearly half-a-million egg cells, yet only 400 or so will ever get the opportunity to create a new life.

  • schiesl

    Fascinating list. There are some spelling errors however. The fact about the blood traveling in 60 seconds is amazing. also i would love to boil water by myself!! awesome

  • stevenh

    great list.

    #13 is just weird.

  • CRE

    15 has some problems. Check Livescience, or most other good sources about scientific knowledge. The appendix has 2 vital roles that it plays in your body. First off, it provides aplace where the stuff that you eat can pool, allowing the exposure of your immune system to he material i your bowels, wher it can have longer to develop antibodies than it would in a faster moving area (like the main section of your intestines). Secondly, it provides a place for your body to store the bacteria that your digestive system uses to process food. If you are appendixless, and get a severe digestive illness, your body can lose the ability to restore these bacteria. If that happens, often times you have to receive a feces transplant from a close relative (whose bacteria should be similar to your own). No joke.

    • Dumpeater

      go eat dump

  • robneiderman

    #14. Unless I've been told the wrong thing by textbooks and professors, the eyeball does grow. They give that as one reason for increasing myopia/decreasing hyperopia in growing kids. (The distance from cornea and crystalline lens to retina increases in relation to the focal length).

    • matt

      i don’t remember number 14 saying the eye ball doesn’t grow.

  • schiesl

    yeah, 13 is a little weird, i have a friend who is a burn vic. I'm sure knowing that his burn victim counterparts are being healed with foreskin will be very comforting to him…or maybe i just wont tell him…

  • christina

    what i think is more interesting about our kidneys is that they primarily produce 180 l of urine every day! only because of some other mechanisms, it is reduced to approx. 2 litres a day… isn´t that fascinating?

  • MzFly

    Wierd yet interesting list. Although, there are some spelling errors and I had to read #13 twice.
    I didn't know #14 and I'm glad to have that knowledge – my Dad used to tell me I couldn't wear contacts until I was at least 18 because my eyes were still growing..lol

  • Mom424

    Good list!

    I've seen how they grow skin, it is a little misleading. They grow it in sheets, then it is perforated with little slits. So that when you apply it, it stretches and and increases 10 fold in size. Similar to the netting on a bag of onions. Once applied the skin quickly fills in the voids.

    I have also read that the appendix actually performs as part of the lymphatic system, but there is no consensus, or at least last I heard. That could have changed, and I'm too lazy to look it up.

  • romerozombie

    This list is a complete lie. Jfrater is a witch. Burn him. BURN HIM.

  • robneiderman

    I don't know why my comment didn't show up, so I'll try again.
    The eyes do grow with the rest of the body. This is the main reason myopic children get worse and hyperopic children get better as they get older. The length of the eyeball grows in relation to the focal length of the cornea and crystalline lens.
    MzFly: Your dad just didn't want to tell you that you were too irresponsible to wear contacts. The only reason kids don't usually get contacts is because they require more care.

  • Sharki

    CRE – A feces transplant? Please tell me this is a typo.

  • Iain

    I'm sure I heard something recently that made out that the appendix is not entirely useless. I don't recall the details, but it was along the lines of helping the immune system.

  • Kristin

    Wow the picture of the eyeball really REALLY creeped me out, I'm am scared of them! I almost couldn't finish reading you list once I was it………………almost!

  • The human body can survive on Moutain Dew for years but only if the said body lives in their parents basement during that time.

  • rushfan

    Great list. Also, babies are born without kneecaps. :)

  • Quiana

    I like I like!

  • Ro

    Know most of these and I'm delighted to see them compiled in a list.#14 always seemed a bit incredible. I have to convince myself everytime.

  • MarkH

    "In 30 minutes, the average body gives off enough heat to bring a half gallon of water to boil."

    Some perspective would be nice on that one, since clearly the average human body *cannot* boil any amount of water. If it's really something like, "If the amount of heat the body gives off in 30 minutes was all expelled in 5 minutes instead, it could boil water," then maybe.

    Absent further explanation, I'm calling mild shenanigans on this one.

    • uhjdsfhjsdfhjdsf

      Wow you're anal.

  • NN

    Great list. Should come in handy in school. :D

  • caboose

    Truly amazing facts, I also find it great that you used standard and metric.

  • A less depressing list than the lest :)
    Great list.

  • Ro

    About # 15)People chew and eat beatle leaves in many countries, I've done it many times myself.So does that mean my appendix is actually used in the digestion process? I thought it had no functions at all in humans.

  • copperdragon

    I still have my appendix – guess that's why I love eating leaves (lettuce, specifically)

  • Bob

    "From the moment we are born, only one body part never changes in size – the eyeball."

    This simply isn't true. Why do people believe this one?

  • Robeywan

    A physics professor claimed we give off the same amount of heat as a 100 watt bulb. Invite more company in the winter but charge them for added air conditioner costs in the summer.

  • houkama

    caboose: metric IS standard, no? ^__________^ (ok, not for the Americans..)

  • Kreachure

    CRE: Yeah, I checked Livescience, and it says nothing similar to what you said. It says it's probably vestigial. It also says that "does not directly assist digestion".

  • Kreachure

    #14 is technically almost true, because the eyeball DOES grow, but only a few millimeters since you are born, and compared to the rest of the body it's pretty much nothing.

  • Kreachure

    Oh and the eyeball only grows until you're 5 or so, while the rest of your body still has a long way to go…

    • fasi

      thtx vri intresting thou…

  • This was told to a relative of mine who plays the banjo.

    A banjo player is kind of like an appendix: They can both be a big pain sometimes; you don't miss them when they're gone; & no one's figured out what good they are…

    Very Informative list by the way

  • thethema

    Number 13 is not true…..

    The foreskins are placed in a test tube and artificially grown until they reach the size of an average human, at this point they are removed, dressed up nice clothes and sent into the world as a politician.

  • Wally

    Awesome list as usual guys.

    Did you know that the average pubic hair can remain in the corner of my bathroom for up to 8 months? Fascinating.

  • manchild

    this message is for CRE, just wondering if u are the same person that posts on mma.tv forums, jw

  • Csimmons

    wow, very interesting list, a whole basketball court?!?!? damn!

  • I would like to contest fact 15. First of all, your description of why it is now vestigial is quite Lamarckian, we stopped eating leaves so it got smaller? No, I don't believe any modern scientists would support the theory that less leaves lead to smaller appendixes.
    Also, the appendix in humans is comperable to the cecum in grazers, which is a large organ about the size of a pillowcase in horses that aids in the digestion of fiber and cellulose.
    From wikipedia: "Exclusive carnivores, whose diets contain little or no plant material, have a reduced cecum; often partially or wholly replaced by the vermiform appendix."
    Thus the origins of our appendix, we do have a cecum, but it is very small and would have been our appendix in a common ancestor, however genetic changes over many thousands, millions even, of years has lead to a reduced cecum and the debatably useless appendix.

  • miriah

    With the question on the feces transplant….no its not a joke. Very gross and rare..but yes..you would need feces from a relative to replace bacteria and such in your intestines.

  • Shaks

    Yeah i read about the last one. We used our appendix to digest tough material like Tree bark …. pretty useless now or maybe not with the way things are going with the oil and food shortage maybe this would be in use lol

  • robneiderman

    It's just occurred to me that humans DO eat raw leaves. Usually dripping with Italian dressing.

  • alexlwe

    I would totally repopulate the entire planet in just six months.

    • Steve

      You would have to be able to get laid first, and you hand doesn’t count.

  • Nelia

    Cool list. Lots of interesting info in the comments as well. Oddly, that eye has almost my exact eye color, though mine aren't quite as bloodshot :)

  • Barack Obama

    JFrater–I won the movie drawing over a month ago and followed up with a email 5 days ago…Radio silence. What's the deal?

  • MPW

    very entertaining and interesting list.

    i always wanted to know why there are multiple colors for eyes?

  • copperdragon

    its kinda odd that teeth don't grow back…
    they grow when you're a baby, then they grow when you lose the baby teeth. but if you lose one after that, tough luck.

  • MPW

    for some people the brain stays the same size too

    teeth should grow back

  • DiscHuker

    how amazing are the bodies that God has created!!

    even the stuff that we all know, and is "old news", is very cool. i have just recently learned the reason behind fevers. brilliant!

  • Major Wood

    If bone is that much stronger than concrete, why don't we build our buildings out of it? I'm going to have the most metal house on the block…

    • Viraj

      Hey but who will keep giving bones.

  • kittym

    Bone is that strong? Tell that to the tree that broke my wrist. :)

  • Mom424

    Copperdragon; That is because you are born with the buds for your permanent teeth already in your head. Some people have an extra set, but they erupt at the same time, they don't remain dormant until you lose a tooth. Have you seen people with extra sets of dentition? It is disturbing. (I had 2 extra bottom teeth pulled when I was a kid, they grew in right behind the first 2)

  • jill

    double check your "facts"

  • There are rare cases of people getting a third set of teeth, or of being born with teeth. Rarer still and, as far as I know, occurring only in children under two or three, is the regrowth of a digit lost to a sharp cut.
    I'd love to reference the aforementioned, but I did read them both, in more than one book, but it was some time ago. I probably still have the books, I have thousands, but where to start?
    My library is organized alphabetically by author, and sub-alphabetically by title when I have several works by the same author…I often wish I had organized following the dewey decimal system.

  • Barack Obama: I haven't received an email from you – it might have been lost in my spam folder – can you resend it to frater at gmail please? I will act on it ASAP.

  • MPW

    is it any surprise bone is so strong

    after all it must protect and support our delicate bodies

  • MPW

    funny but true story, one of my friends actually thought that when a man gets an erection a bone in the penis is why it is so hard.

    i laughed and said then where does it go when you're not "happy"

    he's not the brightest star in the milky way

  • i knew some of those

  • Sunny

    I can personally vouch for #5 I knocked off a toenail once when I ran into something. Took about 6 months to grow back to normal.

    #3 That's a helluva lot of sperm!

  • MPW

    sunny, did you cry

    i took a piece of toenail but it only hurt for a minute

  • MPW

    off

  • astraya

    No 3 – I thought there'd be more jokes about this one! I'm confused – the human gestation period is 9 months, so how can one repopulate the planet in 6 months?
    No 5 – On Tuesday a dermatologist pulled my big toenail off, so I'll get back to you approx 12 Dec.

  • MPW

    i can clear my schedule to perform #3

  • MPW

    i guess it should say inpregnate

    merry christmas you get your toenail back

  • astraya

    Amazing fact 16 – something like .01% of the population has their internal organs reversed eg heart on the right. That may not sound many, but 6 billion x .01% = 600,000.
    (I stumbled across that while looking for more information about appendixes (or appendices).)

    MPW – for some reason I don't think "All I want for Christmas is my big toenail" will ever be a Christmas classic.

  • QwertyBop

    #3: Wouldn't it take at least 9?

  • Hi guys – I have been out for a bit but I will update the list and make corrections that you have pointed out shortly.

    MPW!
    My kids and I are avid collectors of such appellations. This is the very first time I've ever come across this particular one.
    THANK YOU!
    A brand new entry! You're my hero.
    thanks

  • edited and corrected.

  • MPW

    segue, glad i could be helpful:)

  • MPW

    finally somebody acknowledges my hero status.

    you're welcome

  • billyrules!

    "The net day you shrink back to your former height." i found another spelling error, it should be next, instead of net.

  • billyrules!

    and that was on fact #7

  • MPW: 400 comments soon. How do you do it? :D

  • Vera Lynn

    MPW I can clear mine, too. When do you want to start? ;)

    There is a word for a bone in the penis of some animals. And after a day of baking in a room with no AC, my brain is fried. Wish I could. I want to say it's bakula. Something like that.

    Cubs winning again!

  • MPW

    long time commenter, first time complainer

    13- "sized" should be size

    14 Per cent.. isn't it percent?

  • MPW

    Vera your place or mine:)

    warningdontreadthis: i have a lot to say and a lot of free time:)

  • MPW

    i knew a guy who knew a guy who had three full rows of teeth

  • MPW: thanks for the corrections – I have updated the list :)

  • Vera Lynn

    MPW Meet you half-way! Why so much free time? You don't work when school's out? Not that I do. I get a paycheck every 2 weeks like clock-work for the whole summer.

    I've had students with teeth growing out of the top of their mouth (palette). Gross.

  • MPW

    last night i was 6'1" and 8mm now im only 6'1"

  • MPW

    i do work but when im home my computer is always on so i check it frequently

    wheres half way?

    you are welcome J

    400!

  • Vera Lynn

    Was that in reference to #3? WOW! Impressive

  • MPW

    i saw in a video that testicles are a tightly coiled ball of tube like "string" that when straightened are about 10,000 feet or something close to that:O

  • MPW

    hahaha:)

  • MPW

    and to those of you who wear skin tight jeans…stop! you are killing your future sons and daughters

  • Vera Lynn

    MPW Denver Colorado. Does that work for you? I once drove 8000 miles in 5 weeks. The above WOW was for your #77!! :)

  • MPW

    i just got it… hahaha.

    a mile high…hmmm

  • MPW

    i must confess i've never been with an older woman before:)

  • MPW

    Sorry about soriano:(

  • MPW

    he broke a bone in his hand and might be out 6 weeks

  • MPW: hey – I am 6'1" too!

  • MPW

    do your friends and family consider you to be tall?

    in 9th grade i was 5'4" but by the end of 10th i was already 6'1"

    my mom would joke with our relatives by saying "i put him on the rack once a week"

  • Vera Lynn

    MPW I am sick about Soriano. Not because of the team, but what it means to him this season.

    Older women know all the cool tricks. You don't have to take care of us. We know what to do. We get off getting you off. You want more info? Take a chance. And I'm not that much the "older woman"

    I'll put you on a rack. No problem ;)

  • MPW

    i wish i was even taller though

  • MPW

    im sweating over here but im down

    of course i want more info

  • MPW

    avthedemon is a buzzkill

  • Vera Lynn

    I tell my students, especially the girls, that there is power in height. They don't get it yet, but they will. Right now they feel awkward. Im 5'8". It helps to be tall. Not that I'm a giant. I had a graduate who was 6'4"

  • MPW

    the good news is that the cubs are fairly good without soriano but he going to be missed

  • MPW

    5'8" is a good height.

    i graduated with a kid who stood 6'7" but he didnt know how to use his height to his advantage.

    • Steve

      couldn’t learn to dribble worth a damn I suppose?

  • Vera Lynn

    MPW Anywhere, anyway, anyhow. You have struck a chord in me. The answer will never be "no". Don't know why. Cannot explain. avthedemon is a "titface"

  • Vera Lynn

    MPW G'night. You make me smile/laugh every day. Thank you. It is a gift. As are you. Be well.

  • MPW

    good night, talk to you later

  • Cyn

    nice… it only proves that we are not existed accidentally like other`s claim (especially athiests) we are THE masterpiece of GOD AMONG HIS CREATION

    "Eph 1:4 According as he hath chosen us in him before the foundation of the world, that we should be holy and without blame before him in love:"

    AND OUR CREATOR IS THE BEST CREATOR!!! AND WE CAN PROVE THIS IN ALL HIS WORK :

    "Rom 1:19 Because that which may be known of God is manifest in them; for God hath showed it unto them.
    Rom 1:20 For the invisible things of him from the creation of the world are clearly seen, being understood by the things that are made, even his eternal power and Godhead; so that they arewithout excuse:"

  • CRSN

    Lani – i cant find it on youtube for some reaseon, but there is the penis song done by Monty Pythons Eric Idle.

    i played it in class when i was 10 and the teacher absolutly lost it because she thought it was obscene, that was in the 90's, she was in her late 50's, obviosly missed the Monty Python era.

  • jasontimmer

    great list, one minor beef- stomach acid doesn't fail to eat through the stomach wall because of rapidly dividing cells lining the stomach- it is because the goblet cells of the stomach constantly secrete mucus that protects the stomach lining.

    Just a question of intense curiosity: do schools no longer teach spelling and/or grammar? Or is this just a generational gesture______, like Mohawk haircuts (which should have been called Mohegan, aka Mohican) in the 80's, long, unkempt hair on males during the 60's – 70's, choose your country and generation of choice and fill in the blank.
    It has always been thus, but self-styled ignorance of one's native language?
    Bizarre.

  • Cyn

    segue –
    :)
    its an internet thing. and yeah, prolly generational too. (like use of prolly instead of probably…picked up online but find myself using that spelling where ever. kinda scary.)
    given how lazy i am in writing online ..like no caps..i can't get into the 'grammar nazi' stuff. bit of 'pot calling kettle black' in my case. but your point is well taken. what will future generations think of this gobbleygook?
    :)

  • MPW

    i not sure what my generation is called i was born in the late eighties though

    is it Y?

  • MPW

    i am

  • Cyn: After 13 years, K – 12 , of a Catholic school education, followed by 8 years of University, I cannot break myself of ingrained language usage.
    I'm not sorry.
    I understand how easy it could be to fall into the ease of "text-talk", but it so often, to the uninitiated, makes the meaning of the message unclear (which may be the whole point).

    MPW: I have no idea what your generation is called. I tend to call people by their names, think of them as individuals. As I know you by MPW, to me you are MPW, you are not an age, not a generation. Maybe that is the reason I have very good friends whose ages run the gamut from late teens to early 90's.

    My question about the use/abuse of grammar and spelling was one of curiosity, not a put-down of the person who posted. As Cyn seems to agree with my assessment, it's being generational/texting, I suppose it's just something I'll either have to learn or ignore.

  • MPW

    well me too segue, but you can call me Michael or Mike if you feel like it

    not mikey though:)

  • Odd fact: The average human body contains 5 litres of blood. However, in a pregnancy blood volume increases by 40% (sometimes more). So a pregnant woman's blood volume is 7-8 litres.

    I thought it was interesting, anyway. :)

  • MPW: Michael. One of my favorite names. My son's middle name is Michael. Besides the fact that the name is pleasing to both the mouth and the ear, the meaning, "One like God", is powerful.
    Yet I have come to know, and respect, you as MPW, so more likely than not I will continue to call you that.
    My own nick, segue, was chosen on purpose. At this late date in my life, I am in a process of change, a segue, from one way of living to another.
    ****
    Tenebrae: As a woman who has carried three babies to term, I can verify that a pregnant body undergoes some incredible changes.
    How's this for a mind-warping fact? In any other case, a foreign body part would require anti-rejection drugs for one's body to accept, rather than kill, the foreign cells. Yet a baby can grow inside the mothers womb, taking nutrients from the mother, even to the detriment of the mother, and yet the mother's body will not reject the foreign body (the fetus).
    As a rule, the only time an embryo is rejected is when it is not viable, and is usually lost before a woman knows she's pregnant.

  • Unless you consider the Rh factor. If a woman is carrying a positive fetus and she's Rh negative, her body will treat the fetus as an invader and work to destroy it. That's why Rh negative women need to take the RhoGAM shot.

    Only reason I even mentioned it is because I'm a bit pregnant now (again) and only just found the blood bit out.

  • Tenebrae, right you are!
    I did not run into that particular problem, though I could have, so it slipped my mind.
    Rh used to be a nasty little bugger. Now, at least, there is a solution.

  • Sunny

    #56 MPW: I am sure a tear or two slipped down my face as my injured toenail bed gushed blood… but I was too busy swearing up a blue streak to notice. The worst part is later that day after the aforementioned toe was clotted and bandaged…some dumb girl stepped on my toe!! IEEEEEEEE!!!

    #120 Tenebrae – How can you be a little pregnant? :)

  • MPW

    little kids always know when you are hurt

  • Kids are unbelievably perceptive. You simply can't lie to a child about emotions.

  • MPW

    that is true segue but im talking about when you have a boo boo and little kids always hurt you while trying to love you.

    for example if you have a broken arm and your little nephew or niece gives you hug but bumps your arm but you cant get mad even though it really really hurts:(

  • 125. MPW
    Absolutely!
    When my kids were very young, 9mos, 19 mos, and 38 mos, I shattered my big toe and snapped the metatarsal. I was in a walking cast which left my toes exposed, though the big toe was bound. Well, just as things were really starting to knit, my youngest (who had been walking for a month and a half) came over and jumped on my feet to give my legs a hug.
    WOWIE!
    I heard the toe re-break. I nearly keeled over with the pain, and I know I saw stars for a moment, but what could I do? She wanted to hug me! She wanted to make me feel better!
    So I gave her a kiss and have an unbendable big toe to this day.
    Big deal.

    Wow! It's another nice list by JFrater.

    3. A man’s testicles manufacture 10 million new sperm cells each day – enough that he could repopulate the entire planet in only 6 months!~ good one! The man must have to do a lot of coition for that to happen.

    My sister, a hygienist – her DDS is mine too & he told me that teeth continually slowly rise, that is they continue erupting from the gum & only stop when it hits resistance along your bite line. This is not just in youth but later in life. My lower incisors – the top edge had gotten uneven & I asked him to file it down slightly to look better. He said it would not work – the incisors are hitting reistance so if he filed down the left 2 incisors, they would eventually erupt slowly till they hit the bite line & look crooked again. He did suggest “invisiline”, a clear vinyl sort of braces behind the front lower teeth, to straighten them out since they’re just a little crooked. I had metal braces on them in the 1970s…

    Also about the ovaries’ eggs – the most viable eggs a woman ever has is right at birth – perhaps a couple thousand. During her youth they die off so that when she hits childbearing age when she starts menstruating (now age 12 on the average!), only a couple hundred viable eggs are left. So when women like me wait till 32 to have their 1st kid, and start trying 2 years later for their 2nd, they encounter a lot of problems. Any remaining eggs at this point & up to early 40s have genetic problems, thus the higher chances of miscarriages, Downs & birth defects. If you’re close to 40 & able to concieve a healthy baby within 6 months with no miscarriage & no abnormailities, you are very very lucky. About 25% of all pregancies end in miscarriage, altho some are so early (5 weeks) many women do not realize. After a horrible ectopic & loss of a fallopian tube, I had to turn to a fertility doctor at age 36 & after 2 years & several attempts & miscarriages, I was fortunate to finally carry to term. I also had the help of acupuncture – it relaxed me so that my 3rd IVF finally worked. I do believe in the wonders of acupuncture now.

    If you’re 43, a fertility dr will no longer use your own eggs, you have to rely on an anonymous younger egg donor. So when some celeb or famous person is in the media chatting up how she got a baby at age 45 or 51, SHE DID NOT USE HER OWN EGGS. Notice that with a few rare exceptions, she will not confess that she had to rely on IVF, nor that she had to rely on an anonymous donor or even surrogate mother who was paid many thousands of $$ for her service.
    Why the secrecy? There is no shame in this. ‘FESS UP, CELEB MOMS IN YOUR 40s & 50s!!! Tell your real story to help other women who are trying to concieve in their 40s!!!!

    Great list… to RUSHFAN (comment #15) Babies are in fact born with knee caps… my son was born 3 1/2 months premature… only 896 grams & he had knee caps, tiny as they were, they where there. I too was Rh negative, the rograhm shot is usually given @ 26 weeks, I, however, had mine @ 20 weeks due to complications.
    To Segue comment #119: A mother's body can and will reject a baby in any stage. Not only due to the Rh factor but to imbalance of naturally ocurring bacteris, infection in the mother, and various other reasons… It is these reasons I have been given only 1 child and have lost so many.
    Keep the great lists coming!

    Tilda, my heart breaks for you, though I am sure that the birth of your son has been like a balm on the other open sores of loss.

    Of course there are multiple reasons for a mothers body to reject an embryo, but my post # 119 had nothing to do with Rh, in fact, in one of my posts, I made the point that the Rh factor had never been a problem for me.

    What I said, in #119, was "As a rule, the only time an embryo is rejected is when it is not viable, and is usually lost before a woman knows she’s pregnant."
    Notice the modifiers "As a rule" and "usually".

    I know this is *NOT* always the case. My oldest daughter lost her first pregnancy at two and a half months because the embryo was not viable. That didn't make it any less heartbreaking.
    A friend went through a perfectly normal pregnancy until the fifth month, when an infection raced through her body and killed the baby.
    These, as horrible as they are, are the exceptions.

    I have no words to tell you just how sorry I am that you found yourself unable to carry to term. I can only hope that your son, and your family and friends, fill your life with so much love and joy you'll feel full to overflowing.

    “the cells in the stomach lining renew so quickly that the acids don’t have time to dissolve it.”
    This is totally false. The cells would have to grow thousands of times faster than the fastest-growing cancer cells ever seen if they were to be able to counteract teh chemical effects of the stomach acid (which is strong enough to dissolve not only zinc but even stainless steel if left in contact with it long enough).

    In fact the cells are protected by a layer of viscous mucus which they secrete, whioch stops the acid coming into contact with the cells.
