We have all likely felt a sexual attraction to someone. When you see that person across the room at a party and you can’t take your eyes off him or her – that is sexual attraction. It is very different from other kinds of human attraction, like being attracted to someone as a friend or someone you want to work with.

Just because you remember something doesn’t mean that is how it happened. While the human memory is amazing and serves us well, it can be amazingly inaccurate.

To bring this all into focus is Charan Ranganath. He is a professor of psychology and neuroscience and director of the Dynamic Memory Lab at the University of California at Davis and author of the book Why We Remember: Unlocking Memory’s Power to Hold on to What Matters.
