TR, hey kid I'm thinking it stays the way it is.

Creeky joints? I'm running 5K races all summer. Personal best is under 23min. My main job is running operations and teaching classes at my 3 karate schools. I also still compete in karate tournaments at 60yr. old. Two years ago I got the urge to jump again and did 10 sky dives, one from 10 thousand feet.
I think most of that stuff is part of my therapy.

I'm putting you on the list of potenial buyers and I promise to take good care of the I.P.
Happy fathers day to you.....Frank
