I have a higher heat tolerance than most people, it runs in our family. I have also seen people hit with heat stroke/exhaustion at temperatures most of us can easily handle and it can be really scary. Once you have had either of these conditions you will be more susceptible to these problems in the future. LOTS of fluids in advance and during hunts will help dramatically. The other day in the desert of Utah I was drinking 44 ounces of fluid an hour, and didn't have to "go see a man about a horse" for several hours. Know your body and don't take chances with your health.
