@kim @dymaxion sooo much this, one of the ways I discuss this is that younger people - especially those still in school/college - often have lower risk aversion, and don't have to pay for things if they break them. As well as this they're still used to picking up an item to play with it. It's easy to lose this mentality as an adult. Sometimes I'll show someone the apps their phone came with with the attitude of "let's just play around with it". Oh look, a calculator. A calendar. A compass.

@PeachMcD Ages ago I was looking for some books like that, as a customer asked for recommendations. They were all abominable and offensive. I think I reached out to a local Age Concern branch and asked them for suggestions, which turned out to be written for people.
