I think the self propagating ad campaigns are brilliant as well, but I also consider it a problem. Even if I don't care about anyone else, I'd personally rather not smell bad, as I have to be near myself all the time.
You don't notice your own smell. I shower every morning and after a workout, but I don't use 'oder' enhancing products and people have commented that I smell nice. But, it's also possible to stink without noticing it. I think this has a lot to do with diet as I have read that a lot of what people consider 'bad' smells are actually signs that something is wrong with you.
It event doesn't require all that much. Sweat while doing some physical work, wait 12 hours without changing clothes and then do some physical work and sweat again. You'll smell to yourself like your fat uncle when he fixes the plumbing. Body odour changes so if you are younger than 30 or older than 50 you expeirience may vary.
