This news makes me feel very sad.
What an amazing guy to keep on going and achieving all that he did, given his tragic circumstances.
That is remarkable. I'd never heard of him before. Hard to imagine living like that.
I was reading about him in the Guinness Book of World Records a week or so ago. The headline is a bit deceptive saying his spent his life in an iron lung though.
Seem to remember listening to a podcast with him - as one of the last of his generation there wasn't anyone left making and servicing iron lungs, so any spares had to be reverse engineered. He ended up with a guy who's day job is building hotrods doing the running repairs on his.
I talked to a chap in one of the London hospitals who was in a similar position a few years back - not quite as bad, he alternated between a full iron lung and a mobile version that did the job at home when his lungs were in better shape. It was odd to see a bit of ancient tech like that clunking away in a modern hospital environment.
EDIT: Just looked him up, he died a few years after I talked to him, and was the longest-surviving iron lung patient at that time.
