ELI5: Explain Like I'm 5

Body odour and sexual attraction

Okay kiddo, so you know how we all have a smell, right? It's kind of like how dogs sniff each other's bums to figure out if they like each other or not. Well, for grown-ups, that smell can be influenced by our sweat - and sometimes that sweat can make us smell not so great.

Now, when we feel attracted to someone, it's usually because we like the way they look, their personality, or the things they do. But did you know that our noses can also play a role in who we find attractive? That's right - some people are attracted to the way others smell!

Now, here's where it gets really interesting. Our bodies produce different types of sweat in different places. For example, our armpits produce a certain type of sweat that is full of something called pheromones. Pheromones are tiny chemicals that can influence how we feel and act around other people - kind of like how certain smells can make us feel happy or calm.

Scientists think that these pheromones might play a role in sexual attraction. Some people might be attracted to the way someone's armpits smell, even if they don't consciously realize it! So, while body odour isn't always a good thing, it's possible that a certain type of sweat could make us feel more attracted to someone.

Of course, this is all just one small piece of what makes us attracted to other people. Appearance, personality, and shared interests are all important too! But it's kind of neat to think about how our noses can help us understand our feelings a little better, don't you think?
