The people in there have lived lives. They may be out of touch but they know things. I talk with residents about my hobbies of woodworking, gardening, canning, hunting, fishing, and wild gathered food.
I've learned WAY more with those conversations than YouTube or books could've ever taught me. It's absolutely worth your time.
And nursing homes are always looking for people to spend time with the very lonely residents.
Anyone with a hobby that isn't technology should do that.
