Every year now another Marlboro Man dies. This year it's Darrell Hugh Winfield, who passed away Monday at his home in Wyoming at the age of 85.

The cause of Winfield's death wasn't announced, but the five other dead Marlboro Men have all died from smoking-related illnesses (three by lung cancer and two by emphysema), so we have our guesses.

Winfield, who was the only of the Marlboro Men to have been an actual cowboy, played the iconic character from the late 1960s to the late 1980s.

From the L.A. Times:

A friend described him to the Los Angeles Times in 1975 as a "man's man." He worked on his ranch every day.

"You could look at the different cowboys that we've used and you could argue that they were all the Marlboro man," a Philip Morris spokesman told the New York Times in 1992. "But Darrell is really the Marlboro man."

Little was revealed about Winfield's personal life or those of the other cowboys, part of the mystique of the Marlboro Man.

"No one knows if he is single, married or swings," John Benson, a vice president of the Leo Burnett agency, told the Los Angeles Times in 1975. "We don't show his home. We don't tell anything about the guy, not even his name or where he lives."

...

He never wore makeup, he said, except to hide the occasional scratch on his face. Asked what life might have been like if he hadn't become the Marlboro Man, Winfield answered plainly: Life would have basically been the same.

Winfield is survived by his wife, brother, and six children, as well as grandchildren, great-grandchildren, and great-great-grandchildren.

Last year, former Marlboro Man Eric Lawson died from COPD. In 1992, Wayne McLaren, another former Marlboro Man, died at 51 after a battle with lung cancer. And in the mid-90s, Davie McLean and Richard Hammer, who played Marlboro Men in the 1970s, died from lung cancer.
