Psychologically there are two dangers to be guarded against in old age. One of these is due absorption in the past. It does not __1__ work to live in memories, in regrets for the good old days, or in __2__ sadness about friends who are dead. One's thoughts must be directed to the future, and to things which there is something to be done. __3__ This is not always easy; one's own past is a gradually increasing weight. It is easy to think for oneself that ont's emotions __4__ are used to be more vivid than they are, and one's mind more __5__ keen. If this is true it should be forgotten, and if it is forgotten it will probably not be true.
The other thing to be avoided is clinging to youth in hope of __6__ sucking vigour from its vitality. When your children are growing up __7__ 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, except they are unusually callous. I do not __8__ mean that one should be without interest in them, but one's interest should be contemplatory and, if possible, philanthropic, but not __9__ unduly emotional. Animals become indifferent to their young as soon as their young can look after themselves, but human beings, owing to the length of infantry, find this difficult. __10__
