Just about every paragraph in this article has something that jumped out on me. The story is about Diana Nyad, a 61 year-old radio commentator who is going to swim from Cuba to Key West in 60 hours. Straight. As one of the marathon swimmers quoted says, "I can't imagine doing anything for 60 hours."

There will be liquid mixture of predigested protein, jellyfish stings, and swollen tongues from the salt water. Diana is the record holder for world's longest swim, and is probably going to go $150K in debt because she's only raised $350K of the $500K necessary. It costs that much because there are 22 people helping put this together.

But also, and let's be honest, this is why I'm posting this.

Two men in kayaks will follow Ms. Nyad’s every stroke. They will hold a shark shield — neoprene rods that emit electrical waves to zap sharks that come too close. The waters between Cuba and Key West are a notorious shark playground. But the shield is not foolproof. Just in case it fails, as it did last year in the Caribbean when another woman was on a marathon swim, four shark divers with spears will be onboard, ready to jump.

Lastly:
"Jack LaLanne was 60 when he swam from Alcatraz Island to Fisherman’s Wharf, in San Francisco, for a second time, handcuffed, shackled and towing a 1,000-pound boat."
