John A. Cone, The Man Who Pleases and the Woman Who Charms
“ Physicians tell us that laughing has a direct and positive effect upon one's health. The physical movement caused by a hearty laugh causes the arteries to dilate and the flow of blood to hasten, thus promoting an acceleration of vital processes; and a mental action through stimulating the blood vessels of the brain. He who administers medicine in the shape of wit and humor to the sad heart is most assuredly a "good Samaritan." ”
