Pursue art if anything. It will reset your psychological clock back a few decades and you will be able to do an activity with younger people without coming across as weird.

If anything, a well rounded worldview brought upon by age is conducive to making art that has a grander, more truthful (not necessarily more factual) statement.

I wouldn't worry too much about trying to make grander more truthful statements with art.

Making things for the sake of making things will do. It doesn't even matter if you don't get better at it over time.

Make things (art, food, woodworking, gardens, anything) for the pure joy of creation and playfulness. That seems like a more surefire way to stay young than trying to make statements.
