A recent study found that sleep helped people to be more creative. The study involved 106 men and women divided into two groups. The first group slept for 8 hours, the second group stayed awake. When they were given a simple maths problem, the sleep group was able to solve it significantly faster than the awake group.
When they were given a task to formulate rules, the sleep group was three times more likely to complete the task than the awake group. The results simply explain that memory problems are related to aging. Older people usually have memory problems because they have trouble getting enough sleep.
Vocabularies :
- Involve : make something a necessary condition or result.
- Simply : absolutely, in a way that is natural and plain.
