This book and for that matter the movie has reignited my enthusiasm about the smells.
Whenever I go out for shopping, I stop by a perfumery to try random perfumes. In time, I noticed that I can now identify some of the ingredients of the perfumes. I highly recommend this practice as it also teaches you to identify the quality of fruits/vegetables easily.
At night, I lay down and replay my day. I can still smell the moist in the air before it rained today.
