I think family cohesion comes across in all of this. Our family always ate together, and sometimes it was relatively-late for the era, simply because we waited for Dad to close his business. Eating together was always where we shared the events of the day.
The nerdy bit...perhaps passing on a few pieces of advice that desperate Americans could try out together...the cooking in the kitchen...the open-door approach to people generally, but also, eating REAL unadultareted food. The incidence of mental health issues I am certain has a direct link to factory-produced, highly-processed non-food.
