Longevity means long healthy life. Vedic philosophy says that the long life should be used to achieve spirituality and not for material enjoyment. Generally it is said to be 100 years of life, although very few attain this limit. However, proper concept of longevity is long life must be without any diseases and suffering. Hence the saying ‘Do not add years to life but life to years.’ If we see the life expectancy list of all countries, Japan is number one with 83.07 while India has 68.03 years of life.
