What is that smell?

• Smells are caused by the presence of certain molecules in the air, which our nose receptors detect and send signals to the brain to interpret as different scents.
• Some smells can trigger strong emotional responses and memories due to the way our brains process sensory information.
• Our sense of smell is closely linked to our sense of taste, as many of the flavors we perceive when eating are actually detected by our olfactory system.
• The ability to smell can vary greatly among individuals, with some people having a heightened sense of smell (known as hyperosmia) while others may have a reduced sense of smell (hyposmia) or no sense of smell at all (anosmia).
• Smells can be pleasant and inviting, or they can be unpleasant and repulsive, with certain scents triggering different responses based on an individual's past experiences and associations.
