More than 160 studies performed in time have shown that being happy makes one live longer. Scientist say that happiness is not necessary a “drug” for prolonging your life. But having a positive attitude, seeing the glass half-full leads to a reduction in stress hormones and a boost in immune system function, both of which should lead to a longer life.
According to a study developed in United Kingdom, the results indicated that old people who stated that they were happy or have been for a while had a reduced risk to die over the following five years.
