It sort of makes sense to me, although the things falling into each category seem entirely different from yours. E.g. I've deliberately tried chewing gum, smoking and religious belief to a small extent in the past (and been unimpressed); however, I've never felt the slightest motivation to take up any sort of sport for entertainment (though I sometimes participate in exercise for health reasons) - it's just Not The Sort Of Thing I Do.

When I was a child or young teenager there was a much wider set of Things Other People Did e.g. watching soap operas, reading magazines, paying attention to pop music, wearing make-up, talking about MOTAS, drinking alcohol, drinking coffee, smoking, sitting in cafes, going out to pubs/clubs/gigs/parties... These were things I did not do and was determined not to do, since they were things approved of by people I disliked and who disliked me - a sort of inverse peer pressure. Eventually I got past this b/w division of activities, and tried most of them at least once :-)
