62 years old woman swims from Havana to Key West, without a shark cage

She had more than just people, she had an electronic repeller, too.

> Six ocean kayakers will switch off paddling kayaks mere inches from Nyad's side throughout the journey, towing underneath them electronic Shark Shields that emit a harmless but annoying electrical impulse that repels most species of sharks. Shark safety officers trained to distract any creatures that may get curious will take turns in the water surrounding her.

This is like saying, "I'm going camping in Mosquito Swamp, without the benefit of a tent!" and then climbing into a sleeping bag, and zipping it shut.

As I understand it a physical shark cage makes a swim quite a bit easier by blocking resistance in the water. So this is a lot harder.

I agree with you. There's also the electronic Shark Shields that repels most species of sharks...
