Good rant and good thread
I agree. As I'm getting older my tolerance for my own funk and filth has gone down. That's why I typically try to hit town every few days if possible to get cleaned up. I have come to really hate stinking and feeling dirty. It's tough to get truly clean out in the woods unless you just flat out submerse yourself in a stream or lake. And not to get too detailed, but being a hairy male makes things even worse.
To address the funk of others, I will also do as others in this thread have stated and stay clear of super foul smelling hikers. That's a potential petri dish of nasty bacteria going on there.
