I have a young friend who, like a lot of irritating young people, uses one of those ridiculous vape pens. We were talking recently and he pulled out the device and took a puff. I rolled my eyes. “Why don’t you just smoke a cigarette, like a person?” I asked. “This is the whole problem with your generation,” I continued. “You only know how to do the ‘lite’ version of things.”

“This is healthier,” he said.
