I'm sure 90%+ plus start at that young stupid age when you feel indestructible, and then get addicted. Addiction is powerful.I've never smoked and don't have any idea why people do it. I've always wanted to ask someone why they're a smoker.
Of course smoking is disgusting, but I try not to judge. It's like yelling at someone for being depressed. Of course being depressed is a terrible way to live life, and every self-help magazine tells you to exercise and get to a therapist. Of course depression doesn't just affect YOU, it affects your whole family and all your friends too. But when you're mentally there, none of that matters. And you hate yourself even more for not being able to get over it when other people have.
