My wife did it to me on my 63rd birthday; she bought me a comfort bike, a Giant Serdona ST. She got tired of me telling my doctor that I would exercise while not trying very hard to start at any time soon. That was four bikes, three years and 35 pounds ago. I now ride at least 30 miles a day and get very cranky and restless when I don't get to ride. I've also been taken off of all the blood pressure and cholesterol medications I was on. Just mention the words "bike ride", fast speeds or slow, and I'm ready to go.
