I'm in my sixties as well, and perhaps the whole "hobby" thing is a generational question.

When we grew up, there was no internet and you largely had to entertain yourself or hang out with your friends. I think that spills over into our adult life, where we just reach for things that seem interesting and appealing and fun.

I like to have hobbies that don't have a lot to do with being online, simply because I earn the majority of my living from being online (eBay, Etsy, Etc) so it makes me happy to be able to step away from the computer. However, I watch our kids and they start to get antsy if they have to sit down their phone for more than 5 minutes. I guess all generations look at the younger generations and wonder how the species is going to survive. But it always does!
