And now, deep thoughts, by Alexis Taylor

Alexis comes to me the other day and asks,
"If I cut my finger off, will it grow back?"
"Why not?"
"I don't know, they just don't grow back."
"Well, my arm got better, and my owies get better."

Ummmm, I could not think of a response for that. Why is it that we can injure ourselves horribly and our bones will heal and our skin will regrow. Our blood vessels can mend themselves, and our nerves regeneraete. But our limbs don't grow back? So I replied,

"I'm not sure why. It doesn't make any sense, does it?"

I guess that was enough for her because she didn't ask any more whys. I'm going to have to start reading some deep science books to answer this ones questions.
