You've probably heard the phrase, "Laugh more and live longer," but what does science say?
Long-livers often say that their secret is their sense of humor.
Although a direct link between laughter and life expectancy has not yet been proven, research reveals surprising facts.

In 2016, Norwegian scientists conducted an experiment involving 53,000 people. Volunteers answered questions about their attitudes toward humor, and 15 years later, the researchers compared their answers with the causes of mortality.
It turned out that women with a developed sense of humor were less likely to die from cardiovascular diseases.
Scientists have also found that laughter can strengthen the immune system: it reduces the level of cortisol (the stress hormone) and increases the immunoglobulin IgA, which protects the mucous membranes from infections.
However, humor does not affect the risk of death from cancer, lung disease or suicide.
Mayo Clinic experts add that laughter saturates the blood with oxygen, stimulating the heart and the production of endorphins, the “happiness hormones.”
It also relaxes muscles, improves circulation, reduces stress and even acts as a natural pain reliever.
Laughter also distracts from disturbing thoughts, giving the psyche a break.
Scientists can't yet guarantee that memes will add 20 years to your life, but they will definitely improve its quality.
Especially if you laugh with others: it strengthens social connections, and loneliness, as we know, ages.
