Question

There are two dangers to be guarded against in old age．One of these is undue（过度的） absorption in the past．There is no need to live in memories，in regrets for the good old days，or in sadness about friends who are dead．One's thoughts must be directed to the future，and to things about which there is something to be done．
It is unwise to be too attached to the youth in hopes of sucking vigor from their vitality （活力）．When your children have grown up，they want to live their own lives，and if you continue to be as interested in them as you were when they were young．you are likely to become a burden to them，unless they are cold to you．
I think a successful old age is easier for those who have strong impersonal interests involving proper activities．It is no use telling children not to make mistakes，both because they will not believe you，and because mistakes are an essential part of education．But if you are one of those who are incapable of impersonal interests，and you only concern yourself with your children and．grandchildren，then you must realize that while you can still render them material services，such as making them an allowance，you must not expect that they will enjoy your company．
Some old people are afraid of death．But in fact the best way is to make your interests gradually wider and more impersonal．An individual human existence should be like a river-small at first，rushing passionately past rocks and over waterfalls．Gradually the river grows wider and the banks move back and in the end they become merged（混和）in the sea without any visible break．
The old man who can see life in this way will not suffer from the fear of growing old and death．
