Like his father, he believed in the virtues of riding and of walking, holding that a vigorous body helped create a vigorous mind.26 “Not less than two hours a day should be devoted to exercise, and the weather should be little regarded,” Jefferson once said.27 In fact, Jefferson believed the rainier and the colder the better. “A person not sick will not be injured by getting wet,” he said. “It is but taking a cold bath, which never gives a cold to any one. Brute animals are the most healthy, and they are exposed to all weather, and of men, those are healthiest who are the most exposed.”
