Over seventy? Useless!

With animus refrescandi, while reading ARA online, I stopped at the advertisement for an air-conditioner-that-isn't-quite-an-air-conditioner called Epi-cooler. Since they don't sell it in fan shops (which are having a great summer and July) but only sell it online, they tell you all sorts of things that make it irresistible if you're one of those people who still want to go to the shop. It has "a wall bracket included with plugs and screws" and a standard plug (down with droughts) of the brand or perhaps the Schuko model (1.8 m). And I was just about to order it without specifically asking for divine intervention, when I read that it also has a "Manual in Spanish (also understandable for people over 70)".

What's happening, do people over seventy not know how to read instructions? Are they very, very easy, spoon-fed instructions so that grandparents, when their children buy them the device, won't get confused and will know how to turn it on? Do they also do this with music players? With audiobooks? And with books? Are books easier than these instructions? Can a person over seventy who can't read the instructions for the machine I won't be buying anymore, read this newspaper? Or will we have to create a section for them, next to the "Creatures, to be exact Old devils? I say I won't buy it anymore, this air, because I'm a decade away from seventy and then I'll have to sell it on Wallapop. Oh, no, I won't know how to do that. That is to say, maybe I'll be working, for the sake of contributing, but I won't be able to spend the money on anything technological. Oh, sorry. I meant “technological” gmxtd. Now I don't know what I've touched. I'll have to call a caregiver, but how do you press the red button?
