LHP, don't order that Hoveround just yet. It's never to late too start a regimen. I didn't become a 5K runner until after the birth of my second daughter. It just takes a short, 2 week time frame to establish, and adhere to, any exercise routine. Find something you enjoy and stick with it. The payoff is immense. There are plenty of excursions calling your name.
