From the genetic point of view two very casual encounters are at the heart of our personality. The first concerns how mum and dad met and the second is how a particular sperm cell met a particular egg each having a casual assembly of half of the genome of each parent.

Laughing is contagious. A study explains how the brain responds to someone else laughing. When someone else laughs areas light up in the brain of those listening that correspond to the areas that are activated when they are laughing. If we hear someone laughing, we instinctively copy.

Ever more researchers think that the dark matter behind how we become are our siblings. Husbands and wives arrive relatively late and parents...
