I’ve been using https://containertoolbx.org/ recently to manage my “other distro” requirements. It doesn’t do anything special but works nicely as a wrapper around podman and does all the bind mounts and uid mappings so you can just enter your $HOME as though you have set up your account in a new OS.
I used to think about it a lot when I was younger because it seemed so unfair that life comes to an end. As I’ve gotten older (and closer to the inevitable) I think about it less. Hopefully you’ll get to the point you realise worrying about something you can’t change isn’t productive use of the time you have left. That doesn’t mean you shouldn’t do what you can to eat well, keep fit and put off that final reckoning as much as you can.
