Wasn't it Teddy Roosevelt who said that any son of his that was afraid of getting a broken arm on the football field was no son of his (or words to that effect)? As for bad smells, we mostly learn to find them bad or good; the bad ones are usually the ones you're not accustomed to.

By the way, there are still one or two places in the UK where they traditionally have a monster once-a-year football game: it tends to be along the lines of the Top of the Village against the Bottom of the Village, with hundreds taking part and one or two getting broken arms, legs, ribs, etc.
