No, I am not. Since I first started this old thread, I have made some adjustments.
First, I stopped all riding in wet weather. I didn't enjoy that anyway, so no big deal.
Second, I try to commute across the Bay Bridge during slightly off-peak hours (i.e., at 9:15 am rather than at 8:30 am). It makes a big difference.
Third, I am going to the gym three times a week, working on balance and core strengthening, plus a little upper body weight training. I can now kick butt and take names.
Finally I have less stress at home, since my wife and I split. This was totally unrelated to my motorcycling, but it did eliminate come of my mental fatigue, which has given me better focus when riding. My 19 year old daughter, who lives with me, supports my riding, since that means she gets to use the car.
