Yup and he really doesn't look frail at all. Genetics goes a long way baby!
Imo, Being wealthy and having the time to take care of himself hasn't hurt his longevity either.
At the moment Shatner has lived 3 years longer than his mother did, she passed away in 1992 at 87 years old, and just over 20 more years than his father who passed when he was 69 in 1967. I have heard him say in interviews that he was filming
"The Devil in the Dark" episode of Star Trek when his father passed. away
