  • Hello, this is Six Minute English, I'm Georgina.

  • And I'm Rob.

  • What do you do when you're tired, Rob?

  • Oh, well, I go to bed.

  • Before that, I clean my teeth.

  • But what does your body do to tell you you're tired?

  • Right, well, these days, I just kind of fall asleep in front of the TV.

  • Yes, but okay, what am I doing now?

  • Oh, yes, hang on, yes, you set me off.

  • Yawning.

  • Yes, yawning is a sign that we're tired or bored.

  • Are you tired or bored now?

  • No, not particularly.

  • So why did you just yawn?

  • Well, because you did.

  • That's the thing about yawns.

  • They are contagious.

  • They can spread from one person to another.
