'Star Trek's' Leonard Nimoy diagnosed with serious lung disease due to smoking

Taking to Twitter, the beloved "Star Trek" actor explains that he's been diagnosed with a rather serious lung disease: "I quit smoking 30 years ago. Not soon enough. I have COPD. Grandpa says, quit now!! LLAP [Live Long and Prosper]."

COPD, short for chronic obstructive pulmonary disease, is one of the most common lung diseases. Said to be caused by smoking, COPD makes it increasingly difficult to breathe. It usually manifests as emphysema or bronchitis.

Nimoy took the opportunity to beg his followers to take his lead and put down the cigarettes.

"Smokers, please understand," he implores. "If you quit after you're diagnosed with lung damage it's too late. Grandpa says learn my lesson. Quit now."

He adds, "I'm doing OK. Just can't walk distances. Love my life, family, friends and followers. LLAP."

Take care of yourself, Spock!
