I was surprised with this chapter and how scent affects our lifestyle pretty much. It is very interesting how how smell is very crucial in our life yet many people do not play attention to it. How smell helps us get hungry and smell food better. I was a surprising shocked to hear that our nose can pick up a scent from a mile long beach with just sand, that is crazy! It is interesting how whales and dolphins use there nostrils to particularly live in this world without who wonders what would happen. DNA which is the master mind in controlling our smell does it again by showing me how DNA plays a role in everything in our body. Overall this chapter was short, interesting, and straight to the point, no confusion in this chapter at anytime.
