I’ve been leading a lot of boxing sessions recently. It’s a lot of fun; but, is probably as much or more work than taking the class. I’d like to think of myself as a “high-energy” person; but, I’m starting to get kinda droopy (for me) toward the end of class. Still, if I don’t get punched, it’s a successful class. Of course, my batteries are fully recharged by the time I get home. Even if they weren’t, The Wife is very good at restoring my energy.
