NBC’s “Today” host Matt Lauer had a rough day on the show on Monday. First, he had to interview Miley Cyrus and second, he learned that apparently people over 40 don’t have sex.

By now most people are probably a little more familiar with the Queen of Twerk than they want to be, thanks to Cyrus’s overly sexual VMA Awards show performance and her nude “Wrecking Ball” video. Just in case you were wondering how long Miley’s antics are going to last, she only plans to stick with the sexual phase for a couple more decades, which she revealed in an interview with Matt Lauer that had to be disappointing for him in more ways than one.

Matt: Is it a phase? Is this a phase? Is the sexual side of you, that we’re seeing a lot of, something that’s going to be here for a while and then you’ll be on to something else?

Miley: Well I heard that when you turn 40, things start to go a little less sexual. So probably around 40, around that time, I heard that’s when people don’t have sex anymore, so I guess maybe around then.

Matt: Do you know how old I am?

Miley: I’m going to guess 40.

Matt: I love you again. I’m 55.

Miley: 55? Oh well, then you’re really definitely not sexual.

Awkward. It’s hard to tell whether Cyrus is being serious or just a little catty. It’s typical of younger people to think that 40 is, like, ancient, after all. Either way, Lauer went from loving Cyrus because she thought he was 15 years younger than he really is to being ready to smack her off that stool for suggesting his sex live has been over.

And just in case you were wondering, as far as Cyrus’s sexual antics go, she’s not the one with a problem–it’s you.

“I’m an artist, so I’m hoping that I get a little attention, otherwise my record sales might be a little sketch,” Miley told Lauer. “I don’t ever really plan to offend people, but sometimes that just happens, because I think people aren’t open to what they don’t understand.”

So that’s the problem with the 20-year-old using her body to break some kind of an OMG record–people are too close minded. Good to know.
