, don't worry. The skills will be there. My good friend from film school pretty much knits and crochets whenever she has her hands free. She made a few shirts during our education. She was 19 when we met. So it's there.
And as for other old lady stuff...my grandma knows some stuff she can no longer do due to her Huntington's. But the thing that sticks out is my lat grandads beekeeping skills. I just got given by my mother today the last full jar that remains of the honey that he made. It's a piece of my childhood. My heritage. It will be eaten slowly. With loads of nostalgia, enjoyment and respect.
