This is interesting

A study by the National Academy of Sciences found the levels of oxytocin and another stress-relieving hormone, arginine vasopressin, rise in both adults and children after a cuddle.

Studies at Montreal Children's Hospital also found that babies who were cuddled for five hours a day cried 50 per cent less than the average baby who is cuddled for two-and-a-half hours a day.

Adults laugh on average 18 times a day compared to a child's 200 times a day!!!
Laughter helps everything, from pain relief to aiding the digestive system.
