To be clear, my folks, and I mean both of them, are members of the Silent Generations. They are not Boomers.
All members of the Greatest Generation (ie the generation that precededed the Silent Generation) are now gone. All those who fought for are freedom in WW2, gone.
Therefore, the issue that I'm concerned about my folks in 2040, all things being equal, are warranted. Lots of people, including the late-Queen in England, were part of the same generation of my folks. My folks are more in the younger age of the spectrum of that generation, buying me some time. Therefore, what is happening in 2040 is not top of mind right now.
