An upstate New York man who recently died of lung cancer has a simple message in his obituary: “If you’re a smoker – quit now.”

The Times Union of Albany reports 66-year-old Geoff Turner wanted to warn others not to make his mistake in a self-written obituary published Saturday.

The suburban Albany resident died Feb. 13, about three months after he was diagnosed with stage-four lung cancer.

Turner’s daughter Sarah Huiest says he smoked most of his life. She says her father knew it was a bad habit, but he couldn’t give it up.

Turner said in the obituary that he was “an idiot who made the same stupid decision, day after day.”

The obituary says to remember “life is good — don’t let it go up in smoke.”
