Yeah, for me 78+ is when things get rough in the summer. Then again yesterday evening it was in the low 60's/high 50's and humid as hell. I was sweating like a pig by the time I got home after grocery shopping.
You need to put the pig analogy in context. For example, one of my buddies who is Cambodian often says that he is, "sweating like a dog in a Korean restaurant." So, how were you sweating like a pig?
