"The Great Bird" himself, Gene, went first...and then "McCoy" (who's character, ironically, lived to like a hundred a thirty something) and then later "Scotty", and now "Lwaxana Troi"/"Nurse Chapel"/computer voice/original "Number One" are gone.
It's only a matter of time now before the rest of the very aged old TOS cast starts to drop in short order. Aren't most of them in the mid-to-late 70's now?
I think for some reason it will be "Uhura" next...I dunno why I feel that way...I guess it's because Nichelle Nichols just seems so very...aged and kinda frail looking to me.
"Kirk", "Sulu", "Checkov" and "Spock" all seem fairy healthy and active for their ages. But Shatner, I could see him going out from an unexpected heart attack or something. No warning.
