Galen was a strong advocate of exercises and gymnastics, and eulogizes hunting specially. He recommends cold baths for people in the prime of life. As old age is "cold and dry," this is to be treated with hot baths and the drinking of wine. He thought that wine was particularly suitable for the aged, and that old people required three meals a day, others two meals. He had a very high opinion of pork as an article of diet, and said that the strength of athletes could not be maintained without this form of food.
