Leonard Nimoy is Sick. Prepare for Nerd Agony.

Lung disease, poor fellow.

“I quit smoking 30 yrs ago. Not soon enough. I have COPD. Grandpa says, quit now!! LLAP,” the living legend tweeted, adding his signature abbreviation for the half-Vulcan’s “live long and prosper” motto.

Now, COPD is bad, but it’s not lung cancer. My grandfather’s had emphysema, a form of COPD, for years. He’s 83. So it’s not quite time to go nuts re-enacting the funeral scene from Wrath of Khan.

It’s a drag, though. Smoking really does mess you up.
