Not, definitely not, a sporting person - at any age.
However, the winter before I went to secondary school I had a bout of pneumonia that was bad enough for a trip to hospital and quite a lot of time off school. As a result of still having painful lungs when running in cold weather I didn't appreciate "cross-country" - especially when I didn't get picked for a team sport & therefore sent off on running, which was most times, tbh, I wasn't that popular as a pick since I was pretty crap at most sports.
The best experience I had was halving my standing one afternoon [we "took a number" as we were sent off, at about 30 second intervals and handed it back on our return]. I got a very rare well done for that and a nice hot shower ...
The teacher would check we stuck to the full route, by parking up to watch us passing a couple of points and there was also a spying nosy parker of a neighbour that would tell them if anyone took the "short cut home" !
As an adult, I took up air pistol and air rifle for a few years, and managed some very decent groupings and progressed up the leader table most seasons. Many years later I had an evening with live ammo on an army range, the range officer said that, for in-experienced bods like us, a grouping smaller than a spread out hand would be very good - I managed to get my two closest holes to be less than a couple of inches apart, and the rest a little wider than my palm {and I've got quite small hands}
