I'm 67, been collecting for 35 years and have a moderate size collection.
This question hit home a month ago when I had a large brain tumor removed
and the outcome was less than encouraging (but it ended up fine).
After a lot of thought, decided I'll never sell out before I croak. Just
enjoy having and playing them so much. Told wifee to sell hobby stuff
(far more than just pinball) slowly. Perhaps a couple a month.
