Posting it again, because this topic has been hovering around and over my security theater talk for ages. It’s such a great typical example for why and when humans cannot assess dangers correctly. Here’s the facts.
The head and brain injury charity Headway has produced some statistics on the prevalence of head injuries in the UK. Some of the headline facts are as follows: In 2013/14 a total of 348,934 people were admitted to hospital with an acquired brain injury. That equates to an injury every 90 seconds across the country. Over the same period, a total of 162,544 people were admitted to hospitals for a head injury. This equated to one every three minutes. Whilst men are 1.6 times more likely to suffer a head injury, the number of women experiencing them has risen by 24% of the previous decade.
Here you can see the real dangers for your head:
