People who want to live long and prosper should quit smoking now, Leonard Nimoy says. The actor best known for playing Spock in Star Trek has been diagnosed with the lung disease COPD at the age of 82—30 years after he quit smoking, which he says wasn't soon enough, People reports. "I'm doing OK. Just can't walk distances. Love my life, family, friends, and followers," he tweeted.
"Smokers, please understand. If you quit after you're diagnosed with lung damage it's too late," he added. But despite the illness and his current frail appearance—he was recently seen in an airport in a wheelchair, wearing an oxygen mask—he is still working and keeping Trekkies happy, E! Online notes. "Just taped my comments for Star Trek Fest to be aired on EPIX Feb. 16th," he told followers. "Still enjoying my life."
