Its Never Too Late

Is it ever too late to exercise?  I don't mean "late" as in age, although, I m sure that needs to be a consideration.  I was talking time of day, as in late at night.  I let "Dooit Later" dictate our schedule again today and we did our 30 minutes of a Pilates with Band dvd at 10:15 pm.  I believe "Dooit Later" is an evil twin with "Don't" and both are the spawn of their parents, Mr. and Mrs. "Procrastination".  Now lets consider age, is it ever too late to exercise?  I would have to answer, no...there is... "Sit and Be Fit"
