Just a side note my 80 year old mother uses Linux with keepassxc and has generally more secure processes than many software developers I know (who often use very simple passwords, share them around freely...).
Just to say that we should be careful with our generalisations (I know you didn't start this one).
Why should we be careful? Not trying to troll here, but your mother being an exception to the generalization doesn't mean the generalization is wrong. Nobody said 100% of old people had bad security habits.
