It is the beginning of spring here in the Western Hemisphere, which means it’s time to celebrate the birthdays of Trek royalty. Today is the 83rd birthday of Spock Prime himself, Leonard Nimoy. Mr. Nimoy, who recently disclosed that he has a smoking-related illness called COPD isn’t letting anything slow him down. It was announced recently that he will be hosting two special “space-themed” performances by the Boston Pops in May, featuring music from many science fiction classics, including, of course, Star Trek. More information, including ticket prices, can be found at The Boston Pops website. Mr. Nimoy took to Twitter to mark the day and to thank everyone for their good wishes: Living long and prospering. Great family and friends and 100’s of honorary grandchildren. Many. Many thanks.
