People age very differently. I'm 67 and I suppose I'm about average but I still enjoy quilting, gardening, making things. My Mom is 88 and still quilts although her eyes are failing and her stitches are not as straight as they used to be. She did quit buying fabric about a year ago but still delights in little "gifts". I think there's a danger of letting go of things before we have to. As long as you have reasonable health and the ability to do a thing, by all means, do it.
