A study 62 experts from the London School of Economics and Science found that people who tend to go to bed later have 63 (high) IQs. 64 study authors believe the root of why this is lies in our evolution—because nighttime was a more dangerous place, and our ancestors who were to stay up instead of going to sleep 65 (need) to be more intelligent. Also, 66 (stay) awake into the night was a new idea 67 was attractive to curious minds.
Today, our varying living rhythms may still reflect this. “Perhaps some smart people stay up later because their internal clocks are 68 (simple) different,” Dr. Wai says. “Or, perhaps they stay up later because they tend to be alone, and like being up late at night without distractions to think and solve their 69 (problem).” But if you are a night owl, still remember 70 ( get) your seven to nine hours of sleep.
