A happy old age is one that comes slowly with freedom from pain; for neither one who rapidly grows old nor one who grows old insensibly but with pain enjoys a happy old age. This also depends upon bodily excellences and good fortune; for unless a man is free from illness and is strong, he will never be free from suffering, nor will he live long and painlessly without good fortune. Apart from health and strength, however, there is a power of vitality in certain cases; for many live long who are not endowed with bodily excellences. But a minute examination of such questions is needless for the present purpose.
5.16
The meaning of numerous and worthy friends is easy to understand from the definition of a friend. A friend is one who exerts himself to do for the sake of another what he thinks is advantageous to him. A man to whom many persons are so disposed, has many friends; if they are virtuous, he has worthy friends.
