  > his would be a much more interesting study, though I suspect it would have a much less interesting result. That's my suspicion as well, which makes me hope studies like this don't result a bunch of wasted time/money while people go looking to solve the wrong problem. I'm not prone to feelings of loneliness, but my memory has never been great and I'd like to keep what I have for as long as I can. As I get older I plan to keep learning and engaged in various passions to help keep my mind sharp, and for now at least, I've still got a lot of options, but I'm sure the temptation to not bother doing even the things I enjoy will grow stronger with age. Arthritis or carpal tunnel will take away the instruments and the video games, eye sight problems could make reading harder, bad joints and mobility problems could make travel and outdoor activities less appealing. At a certain point, I could see hitting a wall where the effort doesn't feel worth it and it gets harder to find things to keep my mind active. Fortunately, that won't (fingers crossed) become an issue for a few decades yet in my case, but it's been in the back of my mind for a while, and I'll be looking out for signs of that struggle in my parent's lives as they age.
