Say Cheese: The Hidden Power of Smiling
Smiling — the purest expression of happiness — has the ability to
regulate our blood pressure, strengthen our immune system, lower the
risk of cancer, increase our life by seven years, and provide inner
peace and satisfaction. The good news is that it doesn’t cost a thing,
yet unfortunately, an average adult smiles only 20 times a day (in
comparison, an infant or toddler smiles up to 400 times a day).
