I'd like to have a word with the intelligent designer...

So, other animals can regenerate body parts that are hacked off. Lizards regrow their tails, starfish regrow legs, planarians (flatworms) can basically regrow anything. But humans? The supposedly favored race of God? Not so much. I had my right breast (yeah, guys have them, too) surgically removed last year, and it's just gone. Never coming back.

Why?
