It is a fact that no man improves much after the age of 60 and after 65, most suffer a really alarming decline. I could give some examples, but at the advice of my publisher will refrain from doing so.

I don't know, I think he's just going senile, isn't he?

When you become senile, you won't know it.

The first sign of senility is that a man forgets his theorems, the second sign is that he forgets to zip up, the third sign is that he forgets to zip down.

Often a very old man has no other proof of his long life than his age.

Ever seen an old man just sitting in the sun, taking it easy? It doesn't have to mean he's senile. It may do, but very likely he can snap out of it and put his mind to work again if it gets really necessary. But mostly he finds it not worth the bother. Less trouble just to let things happen.'

Old age is the most unexpected of all things that can happen to a man.

Faults of the mind increase with old age as do those of the features. An old man is incapable of taking up new ideas because he lacks the power to assimilate them, so he clings with crabbed tenacity to the opinions of his maturity. He pompously believes himself able to deal with any problem. Contradiction infuriates him, and he regards it as lack of respect. "In my days," he says, "we never contradicted our elders." He forgets that in his day these same words were spoken to him by his grandfather. Unable to interest himself in what is happening round him and thereby keep himself up to date, he tells stories of his past over and over again; and these are so boring to his younger listeners that they end by avoiding him altogether. Solitude is the greatest evil of old age; one by one lifelong friends and relative disappear, and they cannot be replaced. The desert widens, and death would be pleasant if its rapid approach were not so curiously threatening.

A man that is young in years may be old in hours if he have lost no time.

My belief is that every man after fifty-five is always ill more or less.

Yet there's something ominous about turning sixty-five. Suddenly old age is not a phenomenon which will occur; it has occurred.

Men grow old, but they do not ripen.
