I feel this is the best prescription for staying younger. That's a radical idea. If many kinds of people start gathering, this will provide an opportunity for intergenerational communication. What's good about my school Keio is that it provides education from kindergarten to graduate school. If one joins a club activity, there will be students ranging from 7 years old to late twenties.
Children grow up in a diverse environment.
The environment provides children with an opportunity to learn things they can't learn from peers. Love is about caring for others and wondering whether they are thinking about you as well. I have lots of memories from my school ages. It's good to have attachments. There was an incident I still remember clearly.
