Time can fly by, and it can drag. But how much do we really know about it? This October 2021 episode of Vox's Explained series explores the concept of time and how we perceive it both biologically and psychologically.

Time flies by when you're a child, summers seem endless as a teenager, but before you know it, you're facing your mid-life crisis.

Day-to-day time goes slowly when we're bored, but tends to go faster when we're having fun or socializing.

Why does time seem to pass differently throughout our lives?

Studies show that marijuana makes its consumers feel like time slowed down, while alcohol speeds up one's perception of time.

Why do we experience time the way we do?

Time, Explained is part of Netflix's collaborative series with Vox.

Narrated by actor Joseph Gordon-Levitt, this episode investigates how human beings perceive time through interviews with scientists and psychologists.
