I read these discussions with interest. I normally don't even consider my age as of importance.
About 3 years ago my brother-in-law (87 years old) found he disliked WIN 10. I offered to install 'Classic Shell' on his PC, but he decided to go with Zorin. I installed Zorin 15 Lite for him, and he used it without problems until he passed away last year. His executor has also coped with Zorin without difficulty.
I am forced to admit I am now 87 myself. I use Zorin 16 Pro Lite without problems, and also have the latest Makulu OS on an old PC looking for ideas for Zorin 17.
