When you think you can smell snow, you aren’t actually smelling anything. It’s a sensory experience caused by colder weather, humidity, and the feeling of cold air. The cold slows down air molecules, humidity boosts your olfactory nerves, freezing air hits the nerve that transmits sensations from your face to your brain, and this creates the crisp ‘scent’ of snow.

People who are genuinely happy in their relationships usually don’t post about it on social media. Studies show that someone who’s always gushing about their partner on Facebook is tied to how insecure they are in their relationship – while those who are more secure spend time enjoying their relationships instead of trying to convince other people (and themselves) how happy they are.
