Some days I do it for 4 or 5 hours. Sometimes, I'll even take a break, have some lunch and go for it a second time so now we are talking 9 or 10 hours. Sometimes when I am finally done I am exhausted and hurt in places you can't imagine. I do it enough that I have calluses on my hands so even after nine hours of the same repetitive motion I don't get blisters. It is engrossing. I get fixated. I can't explain it. Sometimes I actually feel like I am at one with my balls! Most of my friends are envious and wish their wives would let them do it as much as they want like I can. My girlfriend totally encourages me to take this time for myself and she never interferes. My mom is 82 and she is also supportive. I know it sounds weird, but when I'm done my mom usually wants to hear about my experience. I'm not sure if it is my old brain or my new brain, but I've got to tell you, it does some crazy stuff to me. Thanks for letting me share how happy golf makes me. Do I need to go to rehab?
