Wrinkles may warn of COPD

London - Smokers' heavily wrinkled faces could be an early warning signal of a serious lung disease, British researchers say.

Investigators at Royal Devon & Exeter NHS Foundation say smokers with pronounced wrinkles are five times more likely than those without marked facial lines to suffer from chronic obstructive pulmonary disease (COPD), Reuters reports.

Researchers studied 149 former and current middle-aged smokers and compared how much they smoked during their lifetime and their sun exposure.
