I read an article that tried to answer the question: Do our animal friends love us? When I hold up a doggie treat, I am not sure if my dog loves me or the treat, but this is not a valid test.
One scientific test ran MRI scans on dogs while subjecting them to odors that were unfamiliar to compare their reactions to other smells that they knew.
The results showed that the dog owner’s scent catapults the canine brain into a frenzy of activity in an area called a reward center. The dogs prioritize the owner’s smell and this, the study claimed, is a form of love directed to their main benefactors. I may be paranoid, but I swear my HVAC unit is trying to use odors to prove if I love it. I’m not attached to any MRI machine that tests my brain activity, but I’m sure that my scan would resemble that of any test dog. Over the past few years, I have smelled the “rotten egg” smell and the odor of gas that triggered my brain to suspect a minor gas leak. Luckily, our HVAC technician took care of it quickly. I was subjected to another HVAC odor test when a period of humid weather caused an algae growth in my drainpipes. Another time I smelled what seemed like a pile of unwashed socks, but it was not a laundry problem. Something “organic” had gotten into the furnace heat exchanger. I prove my love to my HVAC by having it serviced by a qualified HVAC technician at least twice each year. That is when the pleasure centers in my brain get activated as I breathe in the clean and odor-free air with the assurance that my HVAC system does indeed love me.
