Why Do Some People Hate the Smell of Garlic?

Some people hate the smell of garlic because their brain thinks it’s really strong. Imagine you're at a party, and someone eats a whole clove of garlic, your nose sends a message to your brain saying 'This is super smelly!' But for others, that same smell isn't so bad. It's like one person loves pizza, while another thinks it’s too cheesy.
