I just got into biking to get healthier. I bought the 29'er REI Novara Madrona the end of March and use it to haul groceries home, or around town. Then in May I bought the road bike, 48cm 2011 Specialized Dolce Sport Compact which I ride on group rides twice a week. I will be 63 in a few weeks. In just a few short months of (almost) daily riding I have toned up considerably, lost 10 lbs (about 5+ more to go :0) 12 miles with the group is now a breeze and ready to up it. I haul a pretty good load of groceries home on the Madrona, absolutely love the Ortleib bags. The car sits in the garage and have only put 2,000 miles on it since Christmas Eve.
Biking definitely makes me feel younger. BTW .. I have fixed the seat on the Madrona. It's now level. The pic was taken last Spring.
