"An old man, of 84 years of age, of the name of Adam Riffle, near this town, gradually lost his sight in the 68th year of his age, and continued entirely blind for the space of twelve years. About four years ago his sight returned, without making use of any means for the purpose, and without any visible change in the appearance of the eyes, and he now sees as well as ever he did. I have seen the man, and have no doubt of the fact. He is at this time so hearty, as to be able to walk from his house to Reading (about three miles), which he frequently does in order to attend church. I should observe, that during both the gradual loss, and recovery of his sight, he was no ways affected by sickness, but, on the contrary, enjoyed his usual health. I have this account from his daughter and son-in-law, who live within a few doors of me." 15. The _fear_ of death appears to be much less in old age, than in early, or middle life. I met with many old people who spoke of their dissolution with composure, and with some who expressed earnest desires to lie down in the grave. This indifference to life, and desire for death (whether they arise from a satiety in worldly pursuits and pleasures, or from a desire of being relieved from pain) appear to be a wise law in the animal economy, and worthy of being classed with those laws which accommodate the body and mind of man to all the natural evils, to which, in the common order of things, they are necessarily exposed. III. I come now briefly to enumerate the diseases of old age, and the remedies which are most proper to remove, or to mitigate them. The diseases are chronic and acute. The CHRONIC are, 1. _Weakness_ of the _knees_ and _ancles_, a lessened ability to walk, and tremors in the head and limbs. 2. _Pains in the bones_, known among nosological writers by the name of rheumatalgia. 3. _Involuntary flow of tears_, and of mucus from the nose. 4. _Difficulty of breathing_, and a short _cough_, with copious expectoration. A weak, or hoarse voice generally attends this cough. 5. _Costiveness._ 6. An _inability to retain the urine_ as long as in early or middle life. Few persons beyond 60 pass a whole night without being obliged to discharge their urine[72]. Perhaps the stimulus of this liquor in the bladder may be one cause of the universality of dreaming among old people. It is certainly a frequent cause of dreaming in persons in early and middle life: this I infer, from its occuring chiefly in the morning when the bladder is most distended with urine. There is likewise an inability in old people to discharge their urine as quickly as in early life. I think I have observed this to be among the first symptoms of the declension of the strength of the body by age.
