My friends and I saw an internet rumour that when pedestrians are hit by fast cars there feet rapidly shrink which is why the shoes are often lost and could not find a definitive answer and opinion was divided. Two of the people present had also heard this before so we could not dismiss it as a one off. As an addition does this also apply to the driver?

Curiosity, the hunger for learning new things, is generally considered a positive feature. But can it also be a patholgy, when the person is in constant NEED of learning new things, feels bad and depressed when not learning, has concentration problems in everyday life for jumping from a bit of knowledge to another one?
