I think there's some truth to thermostats getting buggered up. I had some severe cold damage to my hands (not quite frostbite) and after that my thermostat changed dramatically, for heat and cold. Have you also noticed a difference in cold tolerance? I do OK with the heat now as long as I allow myself to go a little slower and to get acclimated to it (didn't even THINK about it before). I've done several long rides in the 90-100F range this summer and am doing OK. But as MP notes, I think the Endurolytes have really saved my hiney.
