I find my hobbies, interests, and what I generally care about, changes from time to time. This isn't a bad thing and I'm sure other people my age have the same experience. In fact, I think others are searching for new interests or things to fill their time with. Just because you like something now doesn't mean you have to do it forever or it's not you. I never want my hobbies or interests to feel like a job, I had one of those prior to retiring. I've got a long list of things I'm interested in and probably more than I have time for in the course of my years. My interests evolve.
