What will make you happy? That can be one of the most perplexing questions of the human experience. But it turns out that researchers have been studying large groups of people as far back as 1938, and all those studies leave us with one clear takeaway: "Those satisfied in their relationships were happier and healthier.

"Donald Trump is a phony, a fraud. His promises are as worthless as a degree from Trump University. He's playing members of the American public for suckers: He gets a free ride to the White House, and all we get is a lousy hat." With the GOP establishment looking to build its own wall between Trump and the Oval Office, Mitt Romney calls on voters to start supporting someone else before it's too late. Here's the video of the speech.

+ The big question: Did Mitt hurt Trump. Or did he do him a favor?

+ And surprise! Donald struck back with Romney's alleged request for an endorsement in 2012: "I could've said, 'Mitt drop to your knees' and he would've dropped to his knees. He was begging. He was begging me."

+ Meanwhile, the news cycle moves quickly in this much obsessed-over race. And tonight is the rematch of Trump and Megyn Kelly.

"The rise of American authoritarianism is transforming the Republican Party and the dynamics of national politics, with profound consequences likely to extend well beyond this election." Regardless of your politics, you'll get a lot out of reading Amanda Taub's very interesting piece on the rise of American authoritarianism.

If you're a parent, there's a decent chance you don't exactly get what your kids are doing on Snapchat. And that's partially by design. As the company's founder explains: "We've made it very hard for parents to embarrass their children. It's much more for sharing personal moments than it is about this public display." Bloomberg explains how Snapchat built a massive business by confusing olds. My kids are young enough that I'm still trying to come up with ways to embarrass them in Minecraft.

"‘I still remember, as a kid, you'd have family members from over there suddenly show up at the house. You didn't ask any questions. People would just go back and forth. Immigration wasn't that big of a deal back in the day." These days the border between Mexico and Arizona is a very big deal. In NY Mag, Mark Binelli takes a look at the changing landscape and the disturbing trends: 10 Shots Across the Border.

"Since Spears's divorce, the speed with which scandals spread has only increased, making Wasser, who's as expert at navigating paparazzi as she is at practicing law, Hollywood's complete divorce solution. Divorce is just as heartbreaking for those with their own Walk of Fame star as it is for those without one. But when you're famous, the demise of your relationship can also affect your reputation -- and career." If you're a big time celebrity, Laura Wasser is probably the person you want to call if you're getting a divorce. Or like a lot of stars, you can hire her before you even get married.

"So he took 24 sheets of paper and rolled them into a long tube and put that up against her chest, listened to the other end, and found that not only could he hear the heart sounds very, very well, but it was actually better than what he could hear with his ear." The stethoscope has been around for a long time and has basically come to be viewed as a symbol that means doctor. But with all the new technologies, are its days numbered?

"Its advertised effects are about the same as a cocktail: kava is a sedative used to relieve anxiety and relax the muscles. But, unlike alcohol, kava allegedly doesn't interfere with any cognitive abilities, and, if you hydrate properly, it won't give you a hangover." The healthy hipsters have borrowed a plant used for ceremonies in Samoa and other parts the South Pacific and turned it into the latest cocktail fad. I've participated in a kava ceremony, and for what it's worth, it's better washed down with a few cans of beer.

My kids have been asking a lot of questions about the election, and specifically Donald Trump. So I've been working on ways to have an open and honest dialogue with them (mostly without crying). And that led to my guide: How to Talk To Your Kids About Trump.
