There might be something to this fitness stuff after all:
At 60 he swam from Alcatraz Island to Fisherman’s Wharf handcuffed, shackled and towing a 1,000-pound boat. At 70, handcuffed and shackled again, he towed 70 boats, carrying a total of 70 people, a mile and a half through Long Beach Harbor.
That's pretty neat...Not sure when it would come in handy but you never know: Someday you might end up in a shipwreck as an octogenarian. Best to be prepared!
