“An overstrained sense of manliness is the characteristic of seafaring men. This often gives an appearance of want of feeling, and even of cruelty. From this, if a man comes within an ace of breaking his neck and escapes, it is made a joke of; and no notice must be taken of a bruise or cut; and expression of pity, or any show of attention, would look sisterly, and unbecoming a man who has to face the rough and tumble of such a life. From this cause, too, the sick are neglected at sea, and, whatever sailors may be ashore, a sick man finds little sympathy or attention, forward or aft. A man, too, can have nothing peculiar or sacred on board ship; for all the nicer feelings they take pride in disregarding, both in themselves and others. A "thin-skinned" man could hardly live on shipboard. One would be torn raw unless he had the hide of an ox.”
