Sunday Musing

Unfortunately I didn't do much exercise.  I really don't know the rules of exercise.  Do I exercise before or after I eat?  Do I exercise first thing every morning?  Can I exercise late at night?  Those are the kind of rules that I had no idea about since I just started an exercise regimen.  I walk, however slowly.  I am supposed to walk faster than one mile per hour.  Accordingly I am supposed to walk much faster than this.  Wow, where do I begin?
