Alcohol vs. Cigarettes

In a recent conversation I had with Dennis on alcohol vs. cigarettes:

I can't stand watching people put crap like that in their lungs
I mean, seriously
the liver was designed to take a beating
it's got regenerative properties
lung tissue?  not so much.
 Dennis:  hahaha
 me:  cut a lung in half, and see if that sucker grows back
I mean, lungs are so weak that you need redundancy
liver, you only get one because you should only need one
 Dennis:  HAHAHA
 me:  ex-actly
 

I figure it should be documented.  Wisdom like that comes rarely out of my head.
