Explain That

The other day I volunteered at the local cannery. I spent the morning watching countless open cans of chile pass in front of me on a conveyor belt. My job was to watch the level of chile in the cans to make sure they were filled to the correct level. I didn't eat any of the chili. I haven't eaten chili for months and probably won't eat any chili for a while after staring at it for a few hours that morning. Yet, that night I had gas that was laced with the pungent aroma of chili. How is that possible? Did my body actually absorb the aroma of chili from the air? Did thinking about and watching chili for a full morning transfer the smell to my GI track? Weird!
