from NPR:

"My brother has always been 'work-averse,' " says Ray [Magliozzi], 63. "Now, apparently, even the one hour a week is killing him!"

"It's brutal!" adds Tom [Magliozzi], 74.

The brothers have been taping Car Talk at WBUR in Boston for 35 years, and the show has been a staple on NPR Member stations for the last 25 years. With older brother Tom turning 75 this year, the guys decided it was time to "stop and smell the cappuccino."

And here's what the brothers had to say on their own blog:

RAY: But to our fans, don't be sad. We've managed to avoid getting thrown off NPR for 25 years, given out tens of thousands of wrong answers, generated lawsuit threats from innumerable car companies, and had a hell of a lot of fun talking to you guys.

TOM: And when we listen to the stuff that's in our archives, it still makes us laugh. A lot. We're hoping to be like "I Love Lucy" and air ten times a day on "NPR at Nite" in 2075.
