My daughter, who will be leaving for college in a couple weeks to study aerospace engineering and physics, is actively looking for stable hand jobs. The area of her university is fairly rural and the town boasts the oldest continuously running rodeo in the world, as well as trail rides for tourists, so there are lots of horses around. She actually really enjoys mucking out stalls and grooming horses, and if she gets to ride them for exercise now and then, she'll consider it a top level perq. I told her I think that's awesome because her focus is going to be so cerebral and high-level that something physical and down to earth like that will be a nice change of pace.
Having a side job you like and that relieves a little stress sounds like a great idea.
