I mean if you have already adult kids (or no kids at all) you have lot of spare time, my kid's head coach is 68yo, so he has time to train them twice a week (sometimes accompanied his similar aged friend), he also goes with them to matches (not that often 1-2 a month) while giving lectures at university, third training a week is made by some regular IT guy in his 30s with own small kid(s), but he does it only once a week for 1-2 hours, so certainly doable.
Btw. this is in Central Europe, my kid can go to training by himself with tram/bus. As for the matches, I accompany him if it is in our city, but if it's outside the city then he can either join coach(es), they usually ride kids or not participate in match. We don't have car so can't drive him there. Though soon kid will have to move to higher age league, so not sure what club we will find eventually, the one they are cooperating with is outside the city with like 1+ hour commute one way by public transport, so will certainly look into something closer.
TLDR if my kids were already adult I would have also lot of spare time and teaching/helping kids it's sure more fullfiling than doomscrolling at home. Though I am lazy person, but I was in recent years thinking about helping people instead of doing my work for money, the issue is I don't like most of the people, who need help.
