Alright, I will start with sneezes. Do you hate when someone sneezes and does not cover his mouth? Yes, me too, so let me tell you something. Sneezes travel at 100mph, that is a good reason to cover your mouth. And as well, this is the reason why you cannot sneeze with your eyes open. I have tried, it is impossible...
Everybody has seen grandparents, I am sure. Have you noticed that some of them have quite big noses and ears? That is because they are continuously growing. However your eyes will be the same size for your entire life from the same moment in which you are born.
This curiosity is a bit bizarre. A human head can be conscious from 15 to 20 seconds after it has been severed. I could not believe it, I thought it only happened in films. I remember one chapter of The Simpsons in which this happened. At first I thought it didn't make sense, but now I think it is quite realistic. This happens because there is enough blood in the head to maintain it conscious for some seconds after it has been cut off.
My last curiosity is that
it is impossible to tickle yourself. It is true, I have also tried it. This
happens because your brain predicts what your hands are going to do so it does
not react. However if someone else tickles you it will work because your brain
is not prepared for that.
