>Old age. One of the four sufferings according to buddhism. The others are: Birth, Sickness and Death.
Here is what President Ikeda says of Old Age:
Life loses its dynamism from the moment we lose the passion with which to live it. No matter what our age, we cannot afford to let the flame within our heart grow dim. We do not become unhappy because we grow old. We become unhappy only when we grow ever more unwilling to change as we age.
