I do a little of that bouncing around too, but I don't think that has a lot to do with the brain. I pay for it whenI get home for now it's Alieve time. I worked with a guy one time that had fungus on his feet, he lost a bunch of teeth and he told me he could't see very well anymore. He always said "i'm falling apart". well his mind was ok so I figured that's most of the battle. Anyway it's my job to hug all the old ladies. A nice smile is what I get paid.
