Some of the 60 years worth of manuals get forgotten along the way. That's why you'll sometimes run into people who think you can protect your food from radiation by covering the food with a paper or plastic cover.

Or people who avoid microwaves because of radiation poisoning.

Maybe there's like a compromise where every X number of years, a product will come with a hefty manual which doesn't assume knowledge and starts at the basics as a refresher of sorts.

Cell phones, microwaves, light bulbs, plastic containers.

Actually, what I want more than anything to ship with thick manuals is skincare products. I have these more high end skincare products that came as a set and, let's be honest it was likely a waste of money. But I got it for the "experience," y'know?

Anyway, none of the products tell me how to use them. They don't tell me what order to use them in. They don't tell me how often to use them.

These are all things that you know if you're a girl and you don't know if you're a guy because, like you said, there are years worth of manuals--I just skipped those "lectures."
