Our brains are not like smarties...covered with delicious chocolate...We have an exoskeleton and inside covered with a myelin sheath...that doesn't fully develop until about age 25 years old.

I have played fraternity hockey...have a brown belt in judo...been in two major accidents...one took me out for 1 1/2 years...hit in a crosswalk...and two plus years in amateur boxing...and have the nose to prove it.
