I wonder about a lot of things. I wonder what life would be like if gravity were stronger. I wonder why Americans don't dance more. I wonder why so many people who can afford million-dollar homes get cheapo HVAC(Heating, ventilation, and air conditioning). Collectively, the mechanical systems that heat, ventilate, and cool a building. systems. That last one bugs me more more than the first two, by the way. It weighs on my mind because cheapo HVAC seems so out of step with the rest of a million-dollar home.
