Star Trek actor Leonard Nimoy has revealed he is suffering from chronic lung disease, despite stopping smoking more than 30 years ago.
The man who found fame as the star ship Enterprises' logic-driven first officer Spock is a regular user of Twitter, and announced to his 808,000 followers that he has chronic obstructive pulmonary disease (COPD), an umbrella term for a number of illnesses including emphysema and chronic bronchitis.
The majority of cases of COPD are brought on by cigarette smoke, and Nimoy - who signs off each tweet with the letters LLAP ("live long and prosper") - advised his followers to "quit now".
I quit smoking 30 yrs ago. Not soon enough. I have COPD. Grandpa says, quit now!! LLAP
Nimoy, who is 82, was photographed last month leaving a hospital in New York in a wheelchair, and attached to a breathing apparatus.
