Smoking and going maskless will KILL YOU and COULD KILL THOSE AROUND YOU.
What kind of sap would do either? Why advertise weakness inadequacy indecency and selfish?
Do it if you must but NOT IN PUBLIC. Hide out in dim corners. Sneak around in the shadows like zombies and vampires so you won't be identified. You will still die and you will cause the deaths of others but at least you won't be identified specifically. You will get away with it. Unless you die. Well what do you expect when you play Russian Roulette 24/7? Eventually the one bullet in the chamber will take you out. The goal isn't it of those who play?
