Quit Smoking

No, seriously. There's a reason modern Bardot's teeth are so yellow and jagged and her bangs are yellow/gray. Smoking may seem cool when you're 20 and you may plan to quit before your 30th birthday but we all know you probably won't. Smoking is gross, you smell awful, and everyone hates you for it.
