One of the hardest things about working out is making time for it. In my line of work, you can always justify a few more hours at the office. And more importantly, taking time off feels selfish. But this study helps me remind myself that the extra hour a day is actually better for everyone around me too: Bosses Who Work Out Are Nicer. So now I can tell myself I'm not just doing it for me, I'm making myself a better person for everyone I work around.
