Researchers scouted for [identical] twins at the annual Twin Days Festival, in Twinsburg, Ohio, to find pairs in which one twin smoked and the other didn't, or both smoked, but with a five-year difference between initiation. They found 79 twins, of whom 57 were women, altogether with an average age of 48 years old. Close-up photos of each participants face were shown to a group of plastic surgeons, who had no knowledge of each participants' smoking history. They were told to point out "specific components of facial aging" that were related to smoking, and 57 percent of the time, they were able to spot the smoking twin.

"Smoking makes you look old. That's all there is to it," Dr. Elizabeth Tanzi, a dermatologist at the Washington Institute of Dermatologic Laser Surgery, and who wasn't involved in the study, told Reuters. Besides lung cancer, heart attacks, and strokes, just one more good reason to stop smoking is that it's definitely making you look a lot older."

My youngest brother is 12 years younger than I am and smokes like an erupting volcano.  Just after I came out to him, we were having dinner at a restaurant with me in female self mode, and the waiter asked him if I was his younger sister!!!  He did not quite say I was his much older brother but it was close.  I have since been taken for a younger sister on other occasions.  I am 65, he is 53.
