[quote=moneymaker]I’m pretty sure alcohol does to the liver what smoking does to the lungs.[/quote]
I have a glass of wine with dinner or a beer/two fairly regularly. As far as liver/lungs, not really. The liver can regenerate to a point — as long as you’re not killing cells faster than you can regenerate them, you’re OK.
Smoking pollutes the lungs and the nasties (including polonium/radium, since tobacco takes up radioactives from the soil and concentrates them) stay in you for life.
