Well, I also think there is a line missing from the poll; maybe a: "been there - done that", "I'm winding down from all that" or "a way to long" line.

Reason(s):
Bought the land in '68, had the house built in '71, built 2 pole barns shortly there-after.
Raised a family, along with the chickens, beef cows, geese, ducks, etc. Most of all which have come, spent their time here giving out lessons and experiences and now are gone. Note: excludes family - they keep comin' back.

Did the farming thing, haying, growing some crops, etc don't anymore but still own most of the equipment in-case......
Had a garden that went from maybe 15x20 to over 100x100 which now measures maybe 25x25. Canned, dried, pickled, and froze tons of stuff over the years, not any more, don't think it's worth the effort.

Cut firewood, for personal use and even for sale; still do about 6 full cord a year for personal use.
All-in-all, age is creeping up and like others here, I've "been there - done that" for this lifetime - let alone the "10 years or more".........
