Whats a little humidity?

Lately I've been going on walks "around the block" with my neighbors in the mornings. The block actually comes out to be one mile and we do it twice. It sure feels like more than that...They each have two kids and push strollers and I have Zibby to pull me along. It's probably not such a good idea to go walking around 10:30 am here in GA....lately the weather has been between 80 and 90 degrees (which isn't too bad except...) and over 90% humidity! It's just hot...no, sticky!
