Charles, I think the key is to stay "very busy". I'm still working two to four days a week at Aero Precision Machine, Inc. & building stuff in my shop at home.
Mr. Jim, if staying busy helps you live longer then I still have many more years to go.
I currently have 3 businesses and I am in the process of starting up a fourth. I usually put in 60 to 70 hours a week. I do not know if I was blessed or cursed, but I enjoy working.
When I have time, I tinker with the toy boats some too.
the big new Trump makes so much noice we can not hear the realy important man the US have and the most important things we want to do " modelboating " . You are one of the great one .
