New love? Beware of friends
In fact, the professor said: "When you start a love story you lose at least one affection. If he is a family member with time he forgives you and you are able to recover the relationship, while if he is a friend not, you risk losing him forever. This is not due to an either-or of the new partner, but to the fact that there is less time to devote to the "friend".
This theory is based on the fact that our brain is able to manage up to a maximum of 150 types of relationships. As if life were a game with a maximum number of extras: a new character enters and another in the meantime steps back to let him in the limelight.
Professor Dunbar explained that 150 is the limit number that allows us to be selfless and feel a sense of obligation towards others.
