Interesting didn't know all that.
it's impossible to lick your elbow and I don't know if this is true or not, but I heard that when you sneez, the stuff flies out of your nose at 90 miles per hour.
How interesting. I knew some of these, because i took anatomy and physiology, but I didn't know them all.
This was really interesting. THanks for posting it!
Caitlin
The skin on your elbow is called your weenis. Never put your weenis on the table when you're eatting.
Interesting, i liked that. then again I like things like that.
That was fun to read, and interesting.
Thanks.
Bob
how can it bey that babies have no knew cap, its interesting and i don't get it.
hmm, interesting indeed, even though some are a bit off... or some are not necessarily true (instance: HOw many times the heart beats in a lifetime--everyone lives longer than someone else, or the contrary) especially if you got them out of the net... oh and btw, the ennamel (outermost substane of teeth) is the strongest substance in body--phemur (thighbone)--strongest bone of body.
Babies have no knee caps because their bones haven't yet formed, and all that's there is soft cartilage.
I put my weenis on the table at every meal.
The tip of your nose and the balls of your thumbs are two of the body parts, least sensative to pain.
Wow this is interesting where did you get all this stuff did you google it or something? I've heard from somebody that babies can see when their first being born though I also heard that they can't see until they're either 9 days old or 9 months old one of the 2. Don't know if it's true or not.
I wouldn't think that it's true that a baby can't see until they're nine months old. If you watch an infant, they're looking around way before nine months of age. My nephew is two and a half months old, and he loves to look around at his surroundings, especially now with it being the holidays. He absolutely loves looking at all the lights, decorations, etc.
I know it isn't nine months old, my kids saw long before that.
Maybe nine days, but I seem to remember that they both saw right out of the package.

I knew it was impossible to sneeze without keeping your eyes opened. very interesting
Speaking of useless things about the human body, did you know that when you speak saliva comes out of your mouth although you can't see it? Yeah gross.
Nope, I love this message board. Keep the interesting facts coming, if you can think of anymore. Did you know that you lose something like 50000 brain cells every day?
Did you know that when you sneeze, germs leave your nose at a rate of one hundred miles an hour? Or is that one a myth?
or something like 70000 if you visit here every day.
True enough, lollol. Here's another useless fact. You can tell, almost exactly, how tall a tiny baby's going to be when he becomes an adult. my Gran measured my three-week-old cousin's feet because they looked quite big when she went in to visit Lou and the baby in hospital when he was just a few days old. They were already 6 CM long.
Jen.
interesting
No Joanne, the 500 thuosand something brain cells fact is more like a myth. Although it looks that way with some people. lol. If you loose a brain cell, you can't get it back like most of your other cells. Yo, do loose them gradually over time though.
Actually, the whole thing about your brain not being able to regenerate brain cells is slowly becoming a myth. a Princeton study shows that your cebral cortex can generate new brain cells.

These facts about the body are interesting.
I knew some of these, but not others. Didn't they sneeze on myth busters with their eyes open?
