Have you ever wondered why women are pregnant for nine months and not for a longer (or shorter) period of time? I have…especially when thinking about other animals and their gestation periods. Do you know, for example, which land animal is pregnant the longest? It's the elephant, which can be pregnant for up to 23 months. Almost two years being preggers, can you imagine that? I'd die.
Scientists used to think the length of a women's gestation period was related to the size of her pelvis in comparison to the size of a baby's brain. But a new study is suggesting that a women's metabolism is what actually determines the birth of her baby. What exactly does that mean?…

If you've ever been pregnant, you've surely experienced what it's like to have absolutely NO energy to do anything. Although this characteristic usually subsides after the first trimester, it's usually back with a vengeance the closer you get to delivery. Or, at least, that was the case for me.

I had always thought it was in preparation of what's about to happen once the baby is born, but I never imagined it had any relation to the length of pregnancy. I've always though the human body is a perfect machine and this study proves that once again. We're stay pregnant for nine months because that's all our body's can handle.
