On July 2nd, 2013, I will be 40 years young as I celebrate my birthday today.
That's one of the benefits of being a Muppet: even though they've been around for many years, (and of course there's younger Muppets such as Walter, Pepe, Bobo, 80's Robot, etc.) they still have their sense of humor, and since they're made of cloth, felt, stuffing, etc., they don't have to worry about growing physically old or dying (especially true of Statler & Waldorf) as long as the Muppeteers are around to help maintain their looks.....
