I talked with a friend of mine last night, about his grandfather (raised him and his siblings, like a father). Last year at 95, he cut off two fingers at the tablesaw and cut off the circulation to them and waited for two hours for the relative that was going over that afternoon to get there. (didn't call 911 or use one of those alert necklaces, now 8 fingers)
While he gets seen daily from his "kids", he stays/lives their alone at night, to feel independent (and is in better shape then those a lot younger). The family wanted to unplug everything, but they knew that 1. He'd replug it back in, and 2. Woodworking is still a big part of what he lives for.
At least two of the kids don't know or do woodworking, and I don't know for sure, but I don't think the third does either. I have one of the guided systems and may be sending it all his way, under the auspices of try this for a month and give me some feedback (he can keep the whole thing if it keeps him safe and he uses it, old habits die hard). The Sawstop is another option that most likely will be looked at. But that leaves out other tools, Jointer, cms/scms/ras, etc.. (no Xstop) I am going to try to get over there to see his shop and see if there is anything I know of or can provide (like Grrrippers or other helpful devices). I do know he can't exactly handle huge boards well, which is why I was leaning toward the guided systems, and I am not sure what type of projects he does now. So while I may be able to learn from him as well as watching out for (not gonna intrude), what procedures, tricks, safety devices, etc, have you seen older people using?
Nobody wants to be the one to take this away from the man, as they think it will kill him.
And yes I know, we should all be so lucky to make it that long and still be doing what we love!
