The thing that concerns me is that "I do not think I have any real hobbies." I suggest continuing to work, but perhaps being pickier about where you work. Perhaps there's a dream job you've always wanted to do that up until now wasn't feasible because it doesn't pay enough, like fireman, park ranger, teacher, musician, etc? The key here is to have an obligation (people depend on you) and social interaction. Also, see…
On top of that I'd be very keen to invest in health of both yourself and your family. Dead people do not enjoy wealth, and while the sick sometimes need money to fix themselves up one can argue they do not really enjoy it. Some doctors may help you with a proper preventive plan that involves some recurring tests, I'd certainly invest in that. You may need a few, like: an MD, a holistic doctor and a nutritionist.
Then investigate what it takes to "live healthy" for you. Food (more raw organic produce), exercise/sports (yoga, running, cycling, gym, climbing/bouldering, kite surfing), some spiritual practice (meditation, breathing techniques, some philanthropy). This all can bring a person years of healthy life.
If your are not hung up on the location to live, you may want to explore some over the years. Having 2 places to call your home is well within reach. Then if you are into it, you can build, or remodel a place to your interests: a hobby in itself.
