experimenting on mice. They are studying the relationship between diet and health. At this time, over one hundred experiments are being done in this laboratory.
In one of these experiments, the scientists are studying the relationship between the amount of food the mice eat and their health. The mice are in three groups. All three groups are receiving the same healthy diet. But the amount of food that each group is receiving is different. The first group is eating one cup of food each day, the second group is eating two cups, and the third group of mice is eating three cups.
After three years, the healthiest group is the one that is only eating one cup of food each day. The mice in this group are thinner than normal mice. But they are more active. Most of the day, they are running, playing with one another, and using the equipment in their cages. Also, they are living longer. Mice usually live for two years. Most of the mice in this group are still alive after three years.
The second group of mice is normal weight. They are healthy, too. They are active, but not as active as the thinner mice. But they are only living about two years, not the three years or more of the thinner mice.
The last group of mice is receiving more food than the other two groups. Most of the day, these mice are eating or sleeping. They are not very active. These mice are living longer than the scientists thought - about a year and a half. But they aren't as healthy. They're sick more often than the other two groups.

Many observers wrote about the loneliness and monotony of life on the Plains. Men escaped the oppressiveness by working outdoors and taking occasional trips to sell crops or buy supplies. But women were more isolated, confined by domestic chores to the household, where, as one writer remarked, they were "not much better than slaves. It is a weary, monotonous round of cooking and washing and mending and as a result the insane asylum is 1/3 filled with wives of farmers."
