Living without air conditioning is unimaginable for many. Why would you? Modern technology has given us the power to be comfortable no matter how hot or cold it is outside. There's no reason to choose to be hot, sweaty and uncomfortable. Life is just better with air conditioning. Imagine being trapped in an office with your coworkers, only instead of it being freezing all the time, it's blazing hot. That's a special kind of hell.
Or imagine coming home from a blisteringly hot day to your blisteringly hot home. Sure you might get used to it, but let's not pretend it doesn't suck. Life's better with air conditioning.
Others, especially Europeans, look down on people for using air conditioning. To be fair, the elderly and sick probably need air conditioning. But if you're a healthy human being, there's no legitimate reason to need cold air. It's incredibly wasteful. Air conditioning uses 5 percent of all electricity in the U.S. and costs $11 billion a year. All of that simply because Americans can't handle the heat.
It's summer. Summer is supposed to be hot. Instead of hiding in cold recirculated air, people should go outside and embrace the summer heat. It's all relative anyway—most people in the world live without AC and they get along just fine. Comfort is what you're used to.
