The findings, published in the journal PLoS ONE that mortality data refer to children and young men from Sweden, Denmark, Italy and the UK due to traffic accidents since the year 1751.

The data indicate, the risk of car accidents in the age of boys moving forward. Car accidents are part of the behavior of boys to show masculinity and a willingness to take risks. This behavior is related to the development of the hormone testosterone.
