Then we arise with a feeling of the monotony and automatism of life. There is no good, glad refreshing. We feel tired to start with. And so we protract our day-consciousness on into the night, when we do at last begin to come awake, and we tell ourselves we must sleep, sleep, sleep in the morning and the daytime. It is better to sleep only six hours than to prolong sleep on and on when the sun has risen. Every man and woman should be forced out of bed soon after the sun has risen: particularly the nervous ones. And forced into physical activity. Soon after dawn the vast majority of people should be hard at work. If not, they will soon be nervously diseased.
