I don't generally do hot tubs either.

I am very unpopular when at a house party, people ask us to get in the hot tub. I will at times, just not my favorite thing, and I cannot stay in long.
If any of you are Seinfeld fans, Kramer said it best in the episode where they were having water pressure issues and Jerry told him to just take a bath. Kramer's response was something along the lines of, "sit in a tepid pool of my own filth!???"
That's kind of how I feel. :rollseyes
