DD and her BF are wholly unsporty and always were. They were hopeless at sport and laughed at because of it. DD is also very dyspraxic. Team sport nonsense is fine for those who can do it but for those who can't often results in bullying and unkindness.
I am similar to dd and school/organised sport ruined my confidence as a youngster.
However, we are all active, always on the go, walk briskly, dash about, etc. DD was very keen on drama, she and bf are very musical - almost professionally so. We all walk about 4-5 miles a day, just as part of life.
I am 65, good bmi, low bp, no pre diabetes, etc, still working, garden hard and have had a very successful career with no issues about working as part of a team.
The team sport/team spirit guff is a load of old boilleaux as far as I am concerned. For those who can't it just fosters misery. Those who can are not team players when they persistently make snide remarks and leave people unpicked on the bench.
@Sportsareanogo play to your son's strengths.
Interestingly, when I go home I occasionally bump into one of the sporty girls from my youth. In their mid 60s, and by their mid 30s, many of them do not exactly look like pictures of health and some have piled the weight on and slowly waddle about the village.
