How many smells can you identify? Which ones are your favorites and which ones do you really not like? Make an amazingly long and diverse list…
“It’s the first sense you use when you’re born. One out of every fifty of your genes is dedicated to it. It must be important, right? Okay, take a deep breath through your nose. It’s your sense of smell, and it’s breathtakingly powerful.”
As it turns out, adults can distinguish around 10,000 different smells. And these smells not only trigger our memories but can also change the way our foods taste. (Give this classic apple vs potato experiment a spin.)
There’s more TED-Ed, senses, and strong odors in the archives, including:
• What causes body odor?
• It’s Okay to Fart: What are farts made of and why are they funny?
• Why do some people have seasonal allergies?
