January… Four baths in the course of the month; soap with sodium carbonate diluted in wine. Make a compound skin lotion by mixing 3 lb. weight aloes, 1 lb. myrrh, 2 egg yolks; combine these and apply to the skin. This is the quantity per person. Apply it before you enter the bath, and have three bucketfuls [of water] poured over you, then sweat, then go into the open air and sponge the ointment off thoroughly. After washing the ointment off, rub down with cooling wine and egg yolks mixed with hot rose oil, then make love.

If your bath routine does not involve pounds of lotion and fragrant mayonnaise, you are not living your best January.
