The answer is it’s not entirely applicable, because there are huge differences between life of ancient and modern people:
1) Time of sleep:
There was no convenience of electric light in old times, so very few people could stay up all night. Generally people were already sound asleep at 9 PM, and got up as early as 4 to 5 AM.
2) Life style-
Ancient people do not have access to the multitude of entertainment as we do today, such as sound and light stimulation in the form of TV, film, cell phone and internet.
3) No electric products-
Mainly no refrigerator, so ancient people did not have access to ice water or cold food.
4) Means of transportation-
Ancient people did not have vehicles like cars, and had to rely on their feet mostly of the time, which results more exercise than modern people.
5) Food-
There was no chemical fertilizers in old times, so all foods were organic.
6) No Western Medicine in ancient times-
So no one could take both Chinese traditional medicine (CTM) and Western Medicine at the same time.
