You are so fortunate to have a spouce who has an interest to carry him in to the very adult world. Back in the '50s and '60s when I was working in various Boston concerns, many of the older women co-workers had husbands who only knew their work. They did it well, but when the time came, they "retired". Those husbands drove their wives up walls. The husbands did not know what to do with all the leisure time they had. During their working years the husbands never projected 40 or 50 years down the road as to what their lives would be upon retirement, and what avocations they could take up to take up their leisure years. Most of them did not even know how to fish! They could not turn a screw, or tighten a bolt. Literally, they were fish out of water. The wives, meanwhile, not only worked a 40 hour week, but also got the meals, did the house work, the gardening, and found time to knit, crochet, sew, etc. If your husband has an old tractor to keep him working, tinkering, count your blessings. Ask him to look at what he has to occupy his time, and to not, evern jokingly, chide you when you cut up perfectly good fabric into tiny pieces, and sew them together for very interesting works of art and beauty.
