The loneliness pandemic

Why the future depends on friendship. It’s enough to pay for services, and not for friendship. It turns out that many people are lonely. And there is nowhere to go away from loneliness. Loneliness kills. We are living in a world where there is an acute shortage of friendship.<br><br>I read in one book that for a person to maintain their mental and physical well-being, they need 12 people in their life. Close people. If their number for a person falls below 6, then he has a "predisposition" to depression.<br><br>I read in another book that loneliness for a person can be as harmful as smoking a pack of cigarettes a day.
