The problem is that way of thinking is so short sighted. It may be true that your children may not want your guns, your collectibles or your shop tools, but perhaps your grandchildren might ??? In fact more then likely someone in your family will enjoy those things and will want to have "grand dad's things" or whatever, down the road.
When my Grandfather was giving away all his tools, I took his Canedy Otto drill press. A beast of a until that was from 1909. I took it because I was raised when you take something, you take all of it and then discard what you don't want later. Anyway I tossed the drill press out into the weeds. Only after he died 2 years later did I retrieve it and rebuild just because he would have liked that.
The point here is, you just never know. Once you sell/give away something you never get it back.
I have no intention of traveling from birth to the grave in a manicured and well preserved body; but rather I will skid in sideways, totally beat up, completely worn out, utterly exhausted and jump off my tractor and loudly yell, "Wow, this is what it took to feed a nation!"
