 I don't want to be too general here. Lots of people know somebody who is in their 80s and is on the ball. There are judges who don't retire and they're still on the bench working with clerks into their 90s. But in the private sector, it's very common for there to be an age gap. If you're a CEO, you have to be – you can't keep serving. When Rex Tillerson was joining the Trump administration from Exxon, this is one of his issues, that he was actually about to hit his retirement age. He served the government, but he could not continue being CEO of a major company.
