Useful exercises are: reading aloud, drill, handball, running, walking; but this is not by any means most useful on the level, since walking up and down hill varies the movement of the body, unless indeed the body is thoroughly weak; but it is better to walk in the open air than under cover; better, when the head allows of it, in the sun than in the shade; better under the shade of a wall or of trees than under a roof; better a straight than a winding walk. But the exercise ought to come to an end with sweating, or at any rate lassitude, which should be well this side of fatigue; and sometimes less, sometimes more, is to be done. But in these matters, as before, the example of athletes should not be followed, with their fixed rules and immoderate labour. The proper sequel to exercise is: at times an anointing, whether in the sun or before a brazier; at times a bath, which should be in a chamber as lofty, well lighted and spacious as possible. However, neither should be made use of invariably, but one of the two the oftener, in accordance with the constitution. There is need of a short rest afterwards.
