? Sounds like pure speculation on your part. I don't begrudge the guy for being physically active. W is a runner and has done a marathon.
I do remember all the exercise in Utah.
This from the Boston Globe:
Perhaps nowhere is Senator John F. Kerry's edgy style more evident than in his recreational pursuits, some of which are just this side of extreme.
Kerry is known to push himself physically, often at high rates of speed, testing his athleticism, endurance, and ability to make quick decisions.
Many 59-year-olds limit their exercise to golf, jogging, or tennis. Not Kerry. Long a proficient windsurfer (in 1998, he was featured on the cover of American Windsurfer magazine), Kerry in recent years has kicked it up a notch with kiteboarding, a new water sport that has occasionally resulted in fatal accidents.
He's also a longtime motorcyclist, airplane pilot, powerboater, and long-distance bicyclist.
Among his more traditional recreational activities are golf, skiing, sailing, and ice hockey, a sport he once played regularly but now plays only on occasion.
