95 year old hiker on Grey's Anatomy we watched last night

My, what a mass of whitish hair, I was thinking, and what a really old man they got to play the 95 year old hiker. Then I thought, my goodness, back in 1977 that man and I gave each other a hearty hug at an interesting affair in Los Angeles. Long time ago, and he looks pretty good, all in all. A decade older than me.
