If you mean to keep as well as possible, the less you think about your health the better. You know enough not to eat or drink what you have found does not agree with you. You ought to know enough not to expose yourself needlessly to draughts.

Context

“Mr. Emerson believed in pie, and was almost indignant when a fellow-traveller refused the slice he offered him. “ Why, Mr.________, ” said be, “ what is pie made for! ” And Colonel Ethan Allen was one of them,—Ethan Allen, who, as they used to say, could wrench off the head of a wrought nail with his teeth.
If you mean to keep as well as possible, the less you think about your health the better. You know enough not to eat or drink what you have found does not agree with you. You ought to know enough not to expose yourself needlessly to draughts. If you take a “ constitutional, ” walk with the wind when you can, and take a closed car against it if you can get one. Walking against the wind is one of the most dangerous kinds of exposure, if you are sensitive to cold.” source
