OK, so I was watching The Biggest Loser with my mom (yes, I realize the biggest loser is me, with my mom a close second.) Anyway, some guy lost 16 pounds, and I said, wow, to lose that much weight in a week, I'd have to cut off my arm or something. She said, well, you'd lose more weight than that if you cut off your arm--it probably weighs, like, 30 or 40 pounds. I was like, no way does it weigh that much!

So how much does the average arm weigh? Is there a standard percentage of body weight that an arm weighs? I don't have a severed one lying around handy, and it's hard to weigh an arm that's still attached because it's hard to make it totally slack and not put any extra pressure on a scale w/my muscles. If I weigh 180 lbs, about how much would my arm weigh?

No, I'm not some sarcastic right-wing Christian fundamentalist trying to mock evolution. I'd like for people who know science to prove to me evolution. I know it's not easy to "prove" evolution, but can you at least show me how evolution is the logical solution?

Do you think that it could be possible in the future of science that cryogenicly freezing of a LIVE not dead human being that may have a terminal desease that they could bring thatm back to life when they have a cure? OR if their is no cure a that time that if they cloned their body so they could possible re-attatch the body part, organ or even their whole head or brain?

I know its FAR fetched, but Science & medicine may hold more amazing things than we could possible imagine.

I thought that the heart beats by automatic electric impulses from the brain. This is what makes the muscles contract, isn't it?
