Our University has a comprehensive Extension program, with lots of on-line information for all sorts of practical learning. I have used them extensively to learn more about vegetable gardening. Our grand daughter enjoys going out and helping with the harvest, and it's easy to slip in little tidbits about how and what needs to be done.
Eldest daughter is honing her culinary skills, and planted her first garden this past spring. Youngest is learning to quilt and makes some of her own clothes, and plans to plant a garden this spring.
What you say may be true of those in Urban areas, but the rural areas are a different matter especially in states where agriculture is still a big part of the economy. Also, there are a lot of books out there about backyard gardening, back yard homesteading, and urban farming. So there's some city folk that are doing stuff too.
When my father had a stroke, I brought him home to recuperate. Just as he was almost ready to go back home, he had to have a bypass operation, and so forth and so on. I took care of him for five years, and was able to keep him out of a nursing home.
We had a deal, he had to do his physical therapy exercises so that he could at least manage to walk with help. He was too heavy for me to manage if he didn't. So he did.
I am so sorry that more people don't do this. I had to take early retirement, and I did incur some expenses, so now I have some debts that I have to pay off. I would do it again.
You sound like you have a lot of knowledge to impart. Is there a 4-H club, or FFA at the local school. Our community college has horticultural classes. If you have anything like this around where you live, they might like to hear from you.
Maybe you could have them take a field trip to the dining area of your assisted living residence and you could answer questions and help explain what life was like back in the day.
My youngest daughter is very busy since she has a long commute, full time job, night school, and family to raise, but she asked me if I would please buy a notebook and tell me what it was like when I was a kid. So I have finally started on that project for her and the future generations.
Last but not least, there are people right here that are trying to learn what they can about the old days in order to prepare for a situation where that knowledge could save them. So don't hesitate to tell us all about it.
Agree with you about 4-H. The kids out here are better prepared than most because it’s a rural area but they’re far behind from what we knew at that age. The ag classes here put kids to sleep with book learning rather than hands on. The home ec is more about team building than cooking and sewing. It takes them a week to sew on a button and not once in 13 years did I ever see their stove turned on.
