I remember hearing an interview with a Canadian researcher who went to Cuba to study how they did something (I forget what, perhaps health care). While visiting a seniors' centre, she saw a bunch of 10-12 year old kids playing checkers with the old people in a common room. Later, she asked the director how they had come up with so successful a program to pair kids with seniors. "What program?" was the reply. "They just come in off the street."
Such a thing is unthinkable where I live. That says a lot.
