Do you know why people close their eyes when they kiss?
You might think, well they feel shy.
I've carried out a survey in the office and here are the answers from my colleagues to this great mystery of the human psyche.
But I'm sorry. We are all wrong. Academics have found out that the real reason people close their eyes when they kiss is because the brain can't deal with more than two things at once. Basically, it means, when people pucker up, the brain finds it difficult to process the sensation if cognitive power is also being used to analyse what we see.
The academics found that the visual field overrides tactile responses - meaning people would struggle to continue kissing if what they were looking at became more difficult to process.
The findings could also explain why people often shut their eyes whilst reading braille or when dancing.
