No, I'm not refering that we can control nature. I'm just saying that nature says that we should probably only be living to about 30 or 40 years old. Medical advancements can easily double that.

By nature, birth rates (I don't know the numbers) are less than what we can accomplish.

I don't think I'm stateing what I'm thinking, correctly. Evolution is trying to help us live longer and reproduce better. We've doubled it's efforts if not more.
