I feel like that's pretty impressive for a show that ended almost 30 years ago. Even the later Deep Space 9 has lost at least 1 by this point, René Auberjonois. And granted it aired 20 years earlier, but all but 3 of the Original Series mains have passed away.
Here's all of their current age status, oldest to youngest:
Patrick Stewart: 82
Brent Spiner/Gates McFadden: 73
Jonathon Frakes: 70
Michael Dorn: 69
Marina Sirtis: 67
LeVar Burton: 65
Wil Wheaton: 50
Even the "baby" of the cast is a half-century old now :chomsky-yes-honey:
"In other news, the entire cast of sci-fi classic "Star Trek: The Next Generation" died today after a freak accident at a cast reunion..."
Brent Spiner as an old man doesn't parse in my brain, and I've seen the one where he plays Soong
Huh he's aged pretty well actually, good for him
I thought Patrick Stewart was waay older than the other adult cast, baldness really does age you
10-15 years older is pretty big when the cast is what? 20-40?
