Sorry but it happens, Father in law for example, a skilled engineer & had a good career in the chemical industry, He was pretty good at IT & highly proficient with Autocad. Yet in his twilight years he simply could not cope with the tech due to dementia, this he found enormously frustrating, He wouldnt allow us to help him! Being scammed & us stopping it became a frequent occurence.I get irritated by this linking of Luddite approaches to 'IT' and old age.
We all get old if we are lucky. Just pray you dont end up in the same boat!
