Everyone wishes to be long life. That is why Kings in the ancient time wished to live ten thousand years. It is, of course, ridiculous, that even we wish to live up to one hundred years, it is difficult.
Why we cannot be so easy to live up to one hundred years, it is because that organs of our body have already worked for us seventy years from which period organs begin to be deteriorated. Since our organs cannot be replaced, the result is death.
When you are going to an old age, you must be careful with eating. Too much wine and meat will bring your life to a state of illness. You shall live your life in suffering.
If you want long life, you must not get sickness. A practice of peacefulness will help you to live longer and on the otherhand, you shall have no illness.
Why a turtle can live up one hundred years or longer, it is because they always live their life n a peaceful state. Never be in a hurry.
Long life does not mean good, but if you can take care yourself by yourself in your daily life, it is worth to live longer since the world basically is beautiful.
