Williamson explained that it’s important he stays physically fit to qualify to do these dives. For that, he follows a strict regimen of 45 minutes in the gym at least three times a day to make sure his back and heart are strong.
In addition, Williamson said his secret to longevity includes a “wee nip of single malt whiskey at night” and a good sense of humor. “Try to develop a sense of humor. If you don’t already have one, it may be tough,” he joked. “There’s no question humor plays a big factor in your ability in your fading years.”
