@Alexgr. Right on!
I'm a tech-lover but I do think we would do well to keep ourselves sharp by practicing cognitive as well as physical skills.
This isn't a new phenomonon though, it's been a common part of the human story. I am excellent with maps and a general sense of direction, in part because I learned to navigate before gps was a thing, and I still reference maps. But it goes much further: I hunt and gather food at certain times of the year. Some friends and I have an annual pickling party where we can and preserve food. Many people would die if they couldn't have access to a grocery store.
The thing is, I'm not much of a hippy or prepper type, it's just that I don't want to lose skills that were difficult to accuire. It's the same reason I do mental and written long form math once in a while instead of reaching for the calc.
Use it or lose it!
The problem is what happens with a new generation that hasn't even learned the skills (and obviously won't be passing them down either)...
