I dunno,
The Human body should be far more refined than It is IMO...

I Itch n sneeze
I burp n fart,
I creak and crack,
I moan and groan,

And somebody tell me why, WHY, WHY do I get these single hairs made of steel wire growing out the side of my ear ????

Things hurt now and then but hey I use no med's of any kind and I can ride a bike like I stole it so I'm good
