Sad to hear that but hopefully it is the right decision for you.
I suspect a number of small businesses owners will have taken the decision that it might be time to retire. Restarting will be a struggle for a lot of businesses. We're lucky in Luton that when the original owner retired around Christmas 2018 his employees decided to take it on. If anything they've increased business by drawing attention to selling film cameras, film and related services. It's not that they can't sell you the latest digital camera, but they won't have it in stock and they can take a couple of weeks to arrive. So they recommend a shop in nearby Stevenage that does specialise more in digital cameras. In that way perhaps the two businesses complement each other. Both shops made the right call by focusing on different aspects of the camera/photography business.
