I had lived in both Greece and Italy from the late 80's, teaching skiing and owning a couple of watersport centres, bars and restaurants. Came back to the UK in 2001 as my Mom need a couple of knee replacements. They went badly and after a few years Dementia took hold and I stayed to look after her. With the help of live in carers, I managed to take lots of sailing courses and qualified as a Yachtmaster Instructor and got an Officer of the Watch Ticket which allowed me to skipper large yachts both sailing and "Gin Palace" type.
When Mom died after 17 hard years I got a job delivering all types of boats around the world and odd bits of teaching.
With no pension my "later" years were looking good.
Then just 3 months after the funeral I was in ICU with T1 which as an added bonus also includes an instant fail on the yearly medical.
At least I was lucky that it didn't happen whilst crossing the Atlantic although burial at sea does have a kind of romantic appeal.
Got to agree with
@Circuspony in that my fitness/energy levels have not returned in the 3 years since diagnosis so wouldn't be up for the challenge even with the a medical pass.
