My answer (a guess) to this lady's question is, man shy-off activities where there are loads of women.
Just because they aren't into pilates, the theatre and tai chi it doesn't mean they aren't creative.
Maybe they are into their cars, woodworking, fishing, golf or lycra-cycling.
You can't turn people into the mirror image of yourself. You take them as you find them. They might get interested in what you like doing and vice versa.
But I doubt men over 60 are quite as "unadventurous" and uninteresting as the writer believes. They may simply have a tendency to be more solitary and less into socialising. Therefore less visible.
The male readers of this blog, many of whom I suspect are in the group complained about, may have something to add.
