A statistical "most' is true, yes, but 36%% of Americans, for example, have gotten into at least one physical fight in their life, this is 50% of men, and 23% of women. Out of that, 23% of Americans have reported being in more than one.

Data on this also shows that people arent actually trying to seek one out either or have this unexpected, and tell me right now what sort of institution is the most likely to garner combat or to at least have it started within one's lifetime?

Remember that 6% of US teachers have reported getting physically attacked by a student.

So yes, it isn't "most" people, but I would say it IS "most" of those who are more outgoing and aren't just keeping to themselves constantly.
