It's not easy, but it is relaxing. When I'm with my bees I have no other cares in the world. The buzzing alone makes sure of that. If I slipped up, they could kill me, so there's also that. But mainly it's just so darned fun and interesting, and not killing bees is a challenge (which is why we've converted our Langstroth hives to top-bar hives, so it's actually feasible to not kill any bees, but it still requires care and attention). When we eventually take up larger animals, I expect much of the same.
