I caught part of a lovely documentary a while back featuring a really old bloke in an old folks home in the western isles, it turns out he owns the island and bought it sight-unseen in his wayward youth on the strength of an advert in the paper and has lived there ever since. He was on first name terms with most of the worlds monarchs and other greats and goods and was talking about his various international gliteratti adventures.
He was asked will all the privilege and wealth and adventure whether he had any regrets now that he was old and he said "I wish I'd planted trees when I was young"
