badfish im gonna guess your probably somewhat a youngster (no older than 35 )and in good health. i too was once invinceable to the heat but to think like that is a sure way to get a one way trip to the hospital. you are better off to get the woork done in the morning hours. im not too sure i believe in that gatorade stuff. i think too much salt and sugar gets the heart working too hard. i think most get enough salt in a regular diet. as for the record heat it has come and gone but i dont remember 110 heat indexs in quite some time . i work outdoors and i love when i step inside the office and the boss says its not that bad out is it? if your going from air conditioned room to a air condition car its easy to shrug off the heat.
