I would be happy to retire at such an early age...but certainly not move into a retirement community or give up biking! I know plenty of "old dudes" who ride just about every day and can whoop my butt in speed. Back when I was in the boy scouts, one of of assistant scout masters was in his late 50s/early 60s when he hiked the entire Appalachian Trail (couldn't through hike...had two stops - 1 for a death in the family and another for getting lyme disease),
