Anosmia is the loss of the sense of smell. It was extremely interesting to read through how Karl Wuensch's life was effected by his diagnosis of anosmia; installing special detectors for odors humans can naturally detect and taking extra caution when cooking. This section of the book allowed me to connect this to a situation lots of individuals are dealing with today.
With the whole COVID pandemic, one of the most common symptoms is losing your smell. (Thankfully) I haven't personally been effected by anosmia but some of the people I know lost their sense of smell months ago and still haven't regained it. Every couple of days or weeks, I see them sniffing very strong smelling candles and perfumes to see if they can smell a small hint of it. It's incredible to see how much smelling we actually do in our daily lives without even realizing it until it's gone.
Being a health science major, I have always been interested in understanding how/why things happen to the body. I was able to find an article from Harvard Medical School that explained how COVID affects the olfactory cells that perceive smell and why it causes the loss of smell. The link is attached below:
