Star Trek legend Leonard Nimoy recently disclosed that he is suffering from a lung disease called COPD (Chronic Obstructive Pulmonary Disease), a condition commonly caused by age and years of heavy smoking.

Mr. Nimoy, who by his own admission was an “Olympic championship smoker” who smoked two packs of cigarettes a day, quit the habit 30-years ago. Despite being smoke-free ever since, the damage was already done.

On Monday night, Mr. Nimoy, looking well, appeared on CNN’s “Piers Morgan Live” to discuss COPD and touched upon the culture that surrounded smoking during the time he picked up the habit. Continue on to see a clip of his interview.
