It could be said that some of the greatest joys in life are experienced through the sense of smell: the salty ocean, a rose, a newborn baby and for some the “new car” smell. But what exactly is the sense of smell and why do we have it? Here is some interesting information about how the sense of smell developed and the ways in which it impacts our lives.
A rose is a rose, but it may smell different to each individual
Scientists at the Wellcome Trust Sanger Institute in Cambridge, UK have discovered that an individual’s unique sense of smell is the result of genes interacting with experience. In other words, where you live and how you live may determine how your nose and brain interpret different smells.
