I've been smoking on and off for 10 years. It's an awful habit, but as you may have heard, it's hard to quit.
I've justified it in the past by expressing my confidence that cancer will be cured before I develop it (I'm only 28), but meanwhile I smell like an ash tray and my senses of taste and smell aren't what they once were. I float back and forth between not caring to quit, wanting to quit badly enough to go a month without a cigarette, and wanting to quit but not badly enough to be successful.
Do you smoke? Why? Do you want to quit? Why or why not? Do you think we will cure cancer soon via gene therapy or nanotechnology? How about curing nicotine addiction, or addiction in general, via neural-nanobot interfaces?
