From psychological stance-how were cavemen's relationships & social connections easier in a way that teens could mimic in a positive way? less stress?

Probably not easier: I doubt that cave-men's relationships were truly "easier, " except that most of their important relationships were right there in the same cave. So all could help each other with any survival issues. This would certainly cut down on social isolation! but any interpersonal conflicts would be right there with you too. No escape through ipods blasting through headphones, in those days. :-).

UTOPIA: You know, i've never had any caveman in psychotherapy. Cant help there. Sounds like social connections and relationships are some sort of problem now and you arent understanding/managing these very well. Might be a good idea to talk with a therapist and sort it out.

Caveman: Don't even know if cavemen spoke a language? Grunt. Uh. Grunt. My guess is that the caveman's life was focused on survival which means that there likely was not a lot of time for higher level activities such as refined relationships. Be careful what you ask for. Would you really want teens acting like cavemen? My guess is that cavemen were not empathic & lacked social skills. Wouldn't go there.

It wasn't that easy : This is a fun question to think about. The recent anthropological research show that hominids had complex social interactions with each other, within the clan. They had a hierarchy and assigned roles in their pimitive societal structure. The way we socialize today, manage our emotions and behaviors, have not really improved that much. The need for dominance, greed or discrimination... Still there.
