> somehow young people have worse communication skills and less friends

I have a feeling that many young people sit behind the screen all the time.

My point doesn't work if you don't even try to socialize. Still have to make an effort and go through the uncomfortable awkward stage when you are shy or lost for words in most interactions.

I know enough no-drinkers who are just fine even with drinking people, that's the matter of empathy and being able to relax and being open without stimulators which is something not a given to people without a practice.
