I too am 57 and most think I'm in my 40's

I have more energy, stamina and brainpower than ever before. I memorize everything I play and receive comments about that. I am very fortunate that I've taken care of myself, not drank much, eaten correctly, never smoked and always worked out (treadmill, weights and my favorite daily saunas).
I can set up and tear down in 5 minutes and go like crazy all day and night.
In addition to playing almost 70 times in October, I run my independent outside chemical sales business for a French company (3 states). Next year I'll drop off to only 25 - 30x per month to spend more sales time.
Thank you dear Lord. HE is the only one who can predict my days ahead, but I plan to make the most of what I've been blessed with.
