I agree. I don't ever remember heat like this. Especially from the direct sun. And I've been a sun-bum (sorta) all my life. I hear you about the excercise issue in cold weather. This probably is of zero help, but I intensify my training in the winter months so that it has become what I expect every winter - the colder the better. Caution: this is a slippery slope for me because gets dangerously close to when I used my training as a form of self-harm. Flip the script and keep fighting. Remember you're worth it to so many people. :-)
