That... was not an easy a question as Trunks may think it is, Vegeta taking a moment to try and think of an answer to it, before replying honestly. "Most Saiyans fall in battle, it's rare to die of old age." It was just the way of their life, they knew it was always a possibility. You won, or you died. Simple as that.

"I believe my father had some older advisors around him, but I do not know their ages. My best estimate is at least over 80. I'm not sure by how far though." Vegeta is well aware of how different Saiyans aged compared to humans, Bulma often reminded him of that... normally via complaining that he looked too young. "The oldest I had known personally at one point would had been Nappa, but I am now around the same age to which he was when he died."
