Last week I got some very disturbing news.
I have lung cancer and my life is something I'm going to lose.
In less than a year I'll be deceased.
I'll have a tombstone that says Rest in peace.

I smoked three packs of cigarettes everyday for over two decades.
Now I'm about to lose everything and I really am afraid.
I died a little more with each cigarette that I lit.
If you're a smoker, you really should quit.
