Leonard Nimoy fell ill last Thursday (February 19) with chest pains and was treated at UCLA Medical Center in Los Angeles, according to news reports. Nimoy, 83, announced in January 2014 that he was contending with Chronic Obstructive Pulmonary Disease (COPD), and Star Trek's Spock believes his years of smoking -- despite having given up the habit more than 30 years ago -- caused it.

Neither Nimoy nor his representatives have publicly commented on his hospitalization, and it's not known whether he's still at UCLA Medical Center or back home. However, Nimoy has been well enough to tweet, using @TheRealNimoy to tweet poetry and profundity. On Feb. 22, he tweeted "A life is like a garden. Perfect moments can be had, but not preserved, except in memory. LLAP." That sign-off, LLAP, of course means Live Long And Prosper.

Meanwhile, Nimoy's fellow Star Trek legends William Shatner and George Takei have taken to social media to offer their best wishes. Takei, on his Facebook page, said, "As you may have heard, my dear friend and Star Trek colleague Leonard Nimoy has been hospitalized with chest pains. I join millions of fans worldwide in my hope for a speedy and full recovery for Leonard, and my thoughts and prayers are with his wife Susan and his loved ones." Shatner, @WilliamShatner, wrote "I am uplifted by the show of love & caring tweeted to my dear friend @The RealNimoy. I join the chorus of well wishers for a quick recovery!"

StarTrek.com, of course, joins in that chorus of well wishers, too.
