Speaking on Jimmy Kimmel Live!, he said: "It would be boring to talk to me about that. First off, I would say, 'Look. If it's what you want to do ... do it! What the hell's it matter what anybody else thinks?' That would be my point.
"That would the first 30 seconds and I guess we'd spend the next hour and fifty nine minutes saying, 'You're almost 80, what's the point?' This is a theoretical exercise, right? I don't know. He's kind of like past prime for like ... right?"
Meanwhile, in the latest teaser for Bruce's interview - in which he is expected to speak about his gender transition - the star admitted the chat was an "emotional rollercoaster".
