I think nursing homes are going to look VERY different by the time we're of an age to live in them. WiFi is going to be a must. Video games and online activities are going to be constant, residents will have their own electronics and they won't be as dependent on staff and family members to have their needs met. If we can manage our weight and deal with any sensory issues as they come up (cataract surgery, hearing aids, etc) I believe the current crop of under forties will be the least affected by dementia so far.
Yeah, I think from a mental health and social interaction perspective, I could see how video games and online activities would make aging easier. For the most part, those types of activities tend to be low effort/high reward, which, let's face it, is part of the reason they're so popular now.
