There's lots of things I find amazing about the human body.

Right now I'm marveling about the size of the human lungs...they're huge! Just Google the size of the human lung. And they weigh about three pounds. Absolutely amazing.

I also learned that...how do I say this...I carved a chunk of skin out of my ankle while shaving and the doctor said that the area of skin on the bone of the ankle heals from the bottom up, so that's why I was still bleeding from the top half of my cut but not the bottom and there's also no way to stitch that area, so the doc put a steri strip on the wound because there's not enough skin to stitch with. Absolutely fascinating.

And the whole process from conception to birth blows my mind.

What do you find fascinating about the human body?
