It was a tweet that set off a storm. Was President Trump admitting to collusion between his campaign and Russia? Was he stipulating that the now notorious June 2016 Trump Tower meeting arranged by his son Donald Trump Jr. really was all about getting dirt on Hillary Clinton from a Kremlin-linked Russian lawyer and not adoption issues as President Trump had earlier claimed?

For the past three weeks, students across India's capital have been attending a radical new course: happiness.

The Delhi government introduced "happiness classes" in an effort to shift the country's academic focus from student achievement to emotional well-being. In a country that uses standardized testing to determine student success, offers a limited number of seats in top universities and sets high expectations, educators have been seeing mental health consequences.

Kittie Weston-Knauer, on the cusp of 70 years old, is the oldest female BMX bicycle racer in the U.S.

When she started competing in the late 1980s, she was often the only woman on the track. It was her son, Max Knauer, a champion BMX rider, who introduced her to the sport when he was 10.

Max, now 40, explains that he planted the racing seed after a frustrating day of his mom playing coach.

Roxanne and Dennis Simmonds knew their son as fearless and strong from the day he was born.

"D.J. came out with shoulders of a linebacker," Roxanne says. "He was the first baby I saw that had muscles."

"He wasn't really afraid of anything," Dennis says.

At night, young D.J. would take the dog with him and circle the entire house, to "make sure there's nobody on the grounds," Dennis says, laughing. "I used to say, 'D.J. where you going? It's late.' He would say 'I'm doing a perimeter search, Dad.' "

Most people familiar with "face-swapping" know it as an innocuous social media feature. An algorithm captures a person's face and pastes it onto someone else's. The result is rarely seamless and often funny.
