00:00This is the famous quote, the sight of tasty food makes a hungry man's mouth water.
00:05And this is actually a very old quote.
00:07It's from a book called The Psychology of Hunger and Thirst by Ivan Pavlov.
00:10Now, Pavlov is famous for his work on classical conditioning,
00:14which is basically when you associate one stimulus with another.
00:17Like, for example, when you ring a bell before you feed a dog,
00:21the dog will eventually associate the bell with food and starts salivating just from hearing the bell.
00:26He says that the brain is kind of like a hungry man's mouth.
00:29It starts watering the second it sees food.
00:31But in this book, Pavlov talks about something else,
00:35how our brains are wired to crave food when we see it.
00:38And then he goes on to explain that the more hungry a person is,
00:42the more intense the brain's craving will be.
00:44And the best way to satisfy that craving is to eat the food that the brain is focused on.
00:48So next time you see some delicious food,
00:50take a moment to appreciate the amazing psychology that's happening in your brain.
