 ... you asking in chemistry world? You asking me?

Your body is solid, you drink liquids, and if you don't die with your blood drain, but your alcohol weekend to waste life and brain, you might just bug...gling....bubble, like a drunk man, to inhale gas, someone far the car in front, your tail gating?

The exhaustion pipe, that is gas, you can breath in a very heavy pollutant city, you might find all cars have an exhaustion pipe?
