B.O. Has 2 Go

Today I smelled a gym rat from across the weight room. His body odor was so bad I almost lost it. If it smells that strong, shouldn't he be able to smell himself? And if that's the case, why doesn't he run downstairs to either wipe some deodorant where necessary or wash his underarms? An odor that pungent shouldn't be allowed to stink up the place. I'm trying to work out my muscles, not work out my breakfast.
