The answer is that we are all still CAVEMEN and are longing for a TRIBE!
Our needs have evolved with time but are still basically the same!
Humans found out that life is difficult (extremely sometimes!).
Being member of a tribe makes life easier!
Being member of a tribe learns you new stuff!
You can also find your mate!
That’s why social networks are working so well!
After all … we are still the same …
CAVEMEN, and we love belonging to a TRIBE!
