There's something overlooked about zookeepers and many other professions: it's done _outside_. Being outside, directly under the sun, makes us happy, regardless of weather or temperature. I don't think one can be happy being inside all of the time (inside the home, the car, the office, the gym, the mall...) I see trash collectors every day, singing while doing their job. It's one of the least considered occupation, and maybe least enviable. Yet if we ever saw an office worker sing, we'd think they'd gone crazy. I think we need to find a way to put a little more Nature in office jobs.
