Professor Chris Smith, of Manchester Met University, unopened the mystery behind contagious yawning, saying that it is a result of increased levels of carbon dioxide in the lungs, therefore if in a group are all relaxing together, it is probable they'll all reach the same elevated level of CO2 at approximately the same time.
Giving the reason to what came first, the chicken or the egg, he said that the egg as a method of reproduction evolved before the chicken.
Thus, the first chicken would have hatched from an egg laid by a "chicken ancestor". So the egg came first.

It was also revealed that hair colour is the result of pigment secretion and it gradually turns gray as the secretion stops with aging.

However, if you try to stimulate laughter in the wrong situation, others do not join in.
