The most decorated late-night host in the history of television meets GQ's Zach Baron in his hometown for a wide-ranging discussion on the cost of showbiz, the art of interviewing, and why he'll never retire.

"Retirement is nonsense. You won't retire. The human mechanism will not allow you to retire," Letterman, who left "The Late Show" show in 2015, told GQ.

David Letterman is no longer a late night talk show host, but he’s definitely not ready to stop working. In a recently published interview with GQ, Letterman talked about his career, including the fact that he plans to continue it.

In show business, I find that I have pretended to be someone I’m truly not,” says David Letterman as he sits with GQ’s Zach Baron at the Indianapolis Motor Speedway, in Indiana, where Letterman grew up.
