Don't let this happen

Don't let this happen...It's Saturday...maybe it's still snowy, cloudy, rainy or just 'blah' where you live...and you've read the paper, had your coffee, made a light lunch, and now it's time to do your workout...maybe because you missed earlier in the week. But first, why not sit down and "just see what's on TV for a second". Two hours later, you're watching the end of when Harry met Sally
