I wouldn't do that. Whatever health benefits you get from not showering have to be weighted against the health problems caused by you banging your head against the wall after that nice girl/guy actually talks to you and you don't even remember what you said because you can see they know that's not wax on your hair.

No, pointing out the health benefits of not showering won't help. Don't mention damp cloths http://www.youtube.com/watch?v=jSJQEl5vcAo

No, thinking that you are not playing the seduction game for whatever reason is not a valid excuse, it's just not playing to win by handicapping yourself. That's not very rational :|

Here's some actual advice related to personal hygiene and appearance in general:

• Shower every day
• Use deodorant everyday after showering (or, you know, just manage to not stink by whatever means necessary)
• Always dress in a way that wouldn't disqualify you in a job interview or a date. You know that ridiculous shirt you wear when everything else is dirty? Throw it out right now and buy another one of the shirts that make you feel confident.
