Thanks for your input Athleticfreak... I've been living your suggestion for quite some time now and thought I'd experiment a little.
Speaking of which... Earlier today I boasted I didn't break a sweat - tonight at a business meeting I nearly collapsed during a presentation from the unbearable heat! My suit was like an oven, sweat was rolling down my back and pooling in the waistband of my pants.
After a big glass of gatorade, I feel fine again.
