Ours comes up for renewal in early June, so I will definitely be contacting you nearer the time. The rates are pretty high for over seventy-fives!
It's not clear yet whether our EHIC cards will be valid after January 31st. In any case, I've already said that if I die in Agios Stefanos I'd prefer to be buried there, but I'm not sure how possible that is for those who are not Orthodox. I really don't see the point of flying a bag of bones back to the UK for cremation. So the main issue is hospitalisation and medical repatriation. Since I'm more likely to die of a stroke or heart attack, and in either event only rapid intervention would achieve much, it comes down to accidents.
I know that's a bit morbid - but that's the whole point, really.
