Oh wow, that's terrible news.
Back when I worked as a poker journalist, I had the pleasure of interviewing Thor for a magazine. That man had the most awesome stories to tell and it seemed that he for sure had live his life for the max. Absolute degen legend who insta deserves a spot in the poker hall of fame (but probably won't get one since those ****s seem to only accept americans).
I hope they can find some miracle cure, he's a joy to have around on the circuit.
edit: someone needs to co-write this guy's autobiography. It'd make a hell of a book.
