why didn't people wash in those days long ago？
Well, they did not have water in their house. They carried water from rivers or from holes in the ground (= wells). Towns people bought it from a water--carrier. Sometimes it was expensive; and soap was always expensive. They drank water, of course; and so they were clean inside. They did not think about the outside! And this is true; they just did not like a bath.
Modern life is different. We use a lot of soap and water. And we are all quite clean. However, a few people use too much soap; and they often get ill. Who are these people？
Many young women work as hairdressers. They wash and then "dress" other women's hair. That is their job, and they like it. Young hairdressers sometimes wash dirty heads on a busy day! Their hands are soapy for seven or eight hours; and that is not a good thing. A young hairdresser's hands are often red and ugly; and she must then go to doctor.
Long ago, people ______.

A. often died young
B. did not often have a bath
C. washed every day
D. washed every day and died young
