eating a mint at some time or another, and the reason why this happens is due to the active ingredient called menthol.
When we perceive something to be hot or cold, this is due to electrical signals from the nerves which come into contact with the hot or cold ‘thing’. Our brain then interprets these electrical signals as instructions such as – ‘that is hot, don’t ...
This is a very good question and I’m afraid it is one for which there is no satisfactory answer based on our current understanding of the brain.

stomach acid into the oesophagus. After this then it could be an irritation of the thorax or the phrenic nerve (the nerve to the diaphragm). The mechanism of a hiccup usually involves a strong contraction of the diaphragm, the neck muscles and some other surrounding muscles. Just after the contraction begins we start
to inhale at which ...

This dragging effect is caused as residual air molecules still present in the spacecraft's low-Earth orbit catch ...
