If your balance isn't great, I'd recommend tightening the trucks. By tightening the trucks, you lose some steering manoeuvrability but while you are getting your balance right, you probably won't want to do any sharp steering.
BTW, I do some photos every now and then at the local skate park. Plenty of older skaters, some dads, most of them are business professionals.
I'm an ex-skater myself (sponsored in my day) but thanks to a broken pelvis, I tend to avoid it so kitesurfing is my poison because I don't break hips falling hard on water. The fall happened in my school years so it's not something recent, but I have a slightly twisted side so if I got back into it, I would start doing stupid things again which would put my health at risk.
This is a 40+ year old at the park
