The man who has reached thirty, feels at times as if he had come out of a great battle. Comrade after comrade has fallen; his own life seems to have been charmed. And knowing how it fared with his friends--perfect health one day, a catarrh the next, blinds drawn down, silence in the house, blubbered faces of widow and orphans, intimation of the event in the newspapers, with a request that friends will accept of it, the day after--a man, as he draws near middle age, begins to suspect every transient indisposition; to be careful of being caught in a shower, to shudder at sitting in wet shoes; he feels his pulse, he anxiously peruses his face in a mirror, he becomes critical as to the colour of his tongue. In early life illness is a luxury, and draws out toward the sufferer curious and delicious tendernesses, which are felt to be a full over-payment of pain and weakness; then there is the pleasant period of convalescence, when one tastes a core and marrow of delight in meats, drinks, sleep, silence; the bunch of newly-plucked flowers on the table, the sedulous attentions and patient forbearance of nurses and friends. Later in life, when one occupies a post, and is in discharge of duties which are accumulating against recovery, illness and convalescence cease to be luxuries. Illness is felt to be a cruel interruption of the ordinary course of things, and the sick person is harassed by a sense of the loss of time and the loss of strength. He is placed _hors de combat_; all the while he is conscious that the battle is going on around him, and he feels his temporary withdrawal a misfortune. Of course, unless a man is very unhappily circumstanced, he has in his later illnesses all the love, patience, and attention which sweetened his earlier ones; but then he cannot rest in them, and accept them as before as compensation in full. The world is ever with him; through his interests and his affections he has meshed himself in an intricate net-work of relationships and other dependences, and a fatal issue--which in such cases is ever on the cards--would destroy all these, and bring about more serious matters than the shedding of tears. In a man's earlier illnesses, too, he had not only no such definite future to work out, he had a stronger spring of life and hope; he was rich in time, and could wait; and lying in his chamber now, he cannot help remembering that, as Mr. Thackeray expresses it, there comes at last an illness to which there may be no convalescence. What if that illness be already come? And so there is nothing left for him, but to bear the rod with patience, and to exercise a humble faith in the Ruler of all. If he recovers, some half-dozen people will be made happy; if he does not recover, the same number of people will be made miserable for a little while, and, during the next two or three days, acquaintances will meet in the street--"You've heard of poor So-and-so?
