After a week of inactivity (most of it spent in bed) I could really feel it last night when I tried to dance. Muscles were stiff and I tired out before the song was even over. I don't know how I ever survived back in the days when I didn't exercise. And believe me, there were many years of my life like that. Come to think of it, I don't know how anyone can feel good ever without some form of regular exercise. May I never be inactive ever EVER again. Here's to a lifetime of healthy, happy vibrant activity!
