I recently had my 61st birthday....still have the 15# Pearson Power Jet I got when I was 8.
I shoot mostly recurves, but do have several longbows.
Most of my bows are around 55#s, but I still have the first TD bow I ever bought....65# TD Redwing Hunter.
Being old is a state of mind, and you're only as old as you let yourself think you are.
I still hunt from loc-on type stands 16-18' high.
My hunting podna is 74 years young and climbs a tree like a cat squirrel.
I break, start, train, and sell 3 or 4 colts every year....sit around on your butt all the time and you will get OLD in a hurry.
