Like most of us, you're inspired by those ads and slogans exhorting us to get off our butts and "just do it." You know the promise of better physical and mental health is within your reach once you get up and get moving. And you have decided to, just not right now. What's the rush? Where's the fire? You don't want to be too hasty here. You might get hurt if you push yourself too hard. Take it easy, champ. You're not on anyone's timetable but your own.
