The Scythians take kannabis seed, creep in under the felts, and throw it on the red-hot stones. It smolders and sends up such billows of steam-smoke that no Greek vapor bath can surpass it. The Scythians howl with joy in these vapor-baths, which serve them instead of bathing, for they never wash their bodies with water.
HerodotusThose who are skilled in archery bend their bow only when they are preparing to use it; when they do not require it, they allow it to remain unbent, for otherwise it would remain unserviceable when the time for using it arrived. So it is with man. If he were to devote himself unceasingly to a dull round of business, without breaking the monotony by cheerful amusements, he would fall imperceptibly into idiocy, or be struck by paralysis
