In many ways the volunteer job I took just after I retired (due to internal brain melt-down) after 40 years in the NHS was, and is, pretty odd - particularly for me.
Volunteer Canal Lock Keeper - on a stretch of canal without too many boats (max 15/day), but lots of friendly walkers and cyclists, next to a great tea room. Wandering around picking litter if I feel like it, testing lock gates for their sleep-ability - what's not to like? But I'd spent those 40 years working indoors, never mixing with the scary public, and generally getting away with being a miserable git. Volunteering outdoors, with the public, having to be cheerful and helpful - it's just not me - and I love it!
