retirement question

Here's a short except of an interview of Ken Blanchard by Norman Jameson.
Jameson: You're sixty-six. Thinking about retiring?
Blanchard: I asked Zig Ziglar, seventy-nine at the time, if he was going to retire. He said, "There's no mention of it in the Bible and except for Jesus, Mary, David and a few people, nobody under eighty made an impact." He said he was going to "refire" rather than retire.
