Hi donish! That’s really complicated – it has to do with how you’ve grown up, what sort of people you like, and also whether they are interested in you or not. And then there’s the science side: if your genes are compatible with someone else’s, your body will be able to sense that through smelling chemicals called pheromones. But you won’t notice that, it’s all unconscious! We emit pheromones all the time from our skin, and some people notice then and others don’t so much – and they play a big part in how fit other people will think we are and the other way round!
Who have you got in mind? 😉 Sarah
