I recently visited my parents on the other side of the country. My day started at six in the morning, and I didn’t arrive at my mom and dad’s house until nearly midnight. It was a very long and exhausting day of traveling. Despite my early start, the outside temperature was in the mid-eighties with vicious humidity. By the time I parked my car and lugged my suitcase across the parking lot, I was overheated and drenched in sweat. It was a relief to step inside the air conditioned terminal. The process of checking my bag and making my way through the airport security was horrendous. The airport was extremely crowded, with very long longs and lots of irritated people. I can’t imagine the size and scope of the airports HVAC system, but it somehow manages to handle all of the body heat, perfumes, food smells and other air contaminants. When I finally arrived at my gate and waited for the plane to board, the steady circulation of cool air made the experience tolerable. I was not as happy with the temperature or air quality on board the plane. I was far too cold and the odors were overpowering. I then had a layover for several hours in another airport terminal. The food choices for my lunch were not exciting and cost me a fortune. Once again, however, the indoor temperature was a pleasant respite. After spending an entire day inside a temperature-controlled environment, I wasn’t prepared for the heat and humidity when I finally stepped outside at my final destination.
