Essentially tours/activites/travel type of jobs.
1. Hiking tour guide. 2. Give Kiteboarding lessons. 3. Scuba instructor. 4. Travel Writer who goes to different points of the earth and writes about them. 5. Gym trainer. 6. Heli Ski tour operator.
These might seem out there and the pay will be lousy - but I know quite a few kiteboarding instructors and they are some of the fittest and happiest people I have ever known. I'm eventually going to end up like this I think - right after I try founding a few startups. I recently quit my job to start my own startup. (Still in the cycle of customer development).
They have happiness in their soul except when theres no wind and no waves then they become painful to hang around :). But with respect to their health - I dont think I've seen a healthier bunch.
