Yes, but mostly just for the pubic areas because they get oily and just water won't dissolve the oil as mentioned previously. But I thought we already came to the consensus that the soap isn't what kills the bacteria, just very hot water and washing away the bacteria.
On this same line of thought, I think living in areas without a real winter and summer weakens people's constitutions and ability to survive. If you live in a sunny climate year round, you're not going to be able to handle a cold snap. Likewise, if you can't stand the heat of a Texas summer, that makes you a little weaker as well, considering it's only going to get hotter on this planet in the coming decades.
