For me it is because:
1. I have partially torn cartilage in my left knee; bad for a RH bowler.
2. I am getting older (30 this year). I have noticed a difference in my recovery rate the last couple of years.
3. I am not used to it any more. I used to do the 10-20 game thing several times a week when I was learning, around 10 years ago. Now, leagues are the only practice I get any more.
I have gotten used to bowling more often however, because I am in 4 leagues this year and that is the most I have ever joined in one season. Also more tournaments this year, and I have had a couple that lasted 10+ games, and I held up ok.
The day after the tourney is over is quite a different story these days.
