When I was in 5th grade, I had a soccer ball hit me in the nose. More specifically, my brother kicked a soccer ball into my face. Since then, my smell has not been the same and I can handle much more spice. I think this is due to the fact that 80% of taste comes from smell. Because, I can not smell very well either, everything tastes very bland, kind of like I have a cold. I enjoy more spicy foods than I used to and I think this is because they are bolder and I can smell them better. Attached is a picture explaining the close connections in the two sensory origins in your brain.
