5. The Voices In My Head

As a college student, research psychologist Eleanor Longden began hearing voices in her head. The voices started innocuously and became increasingly antagonistic, and she was eventually diagnosed with schizophrenia.

6. A Simple Way To Break A Bad Habit

Why is it so hard to stop smoking or lose weight when we know these habits are bad for us?

What's the most accurate indicator of future academic or professional success? You might think it's IQ, good lucks, talent, physical health, or even family income.
