Sometimes when I'm swimming laps, I hear in my head, "Rarely have we seen a person fail.....etc."  Something about exercise makes your mind get in gear.  I don't know why that is.  When I do speech therapy for kids who don't talk much, I try to take them to a playground.  In most cases, once their bodies are active, their minds kick in, and they start talking.  So I think it's great to excerise and work the aa program at the same time!  It's like yoga keeping my mind and body balanced while I repeat the serenity prayer.  Whatever it is, it's very cool.
