A tricky one this week as we dig into the human body and ask the all important question about ourselves ... why can't you tickle yourself?
Because the brain knows where the touch is coming from and doesn't invoke a reaction (laughing) was the clear winner with 67% of the votes selected from the following:
Just to be boring, laughing when tickled is a natural reaction and is actually caused by panic. It's a response to things crawling on your skil apparently. Even when you know someone is going to tickle you, it still invokes a response as, so I've read on the internet, there is still a part of you that doesn't know if you're going to get hurt and this causes you to laugh. Not sure I follow all of this. I suggest you try for yourself - go stand in front of the mirror in the bathroom and try tickling yourself to see whether or not you can do it.
I think the person that said they can tickle themselves should video themselves and post it on YouTube.
