Our series, "Take A Number," is exploring problems around the world — and the people who are trying to solve them — through the lens of a single number.

Twenty-one days. If you get sued for debt in Utah, that's how long you have to respond to a complaint in the mail.

The complaints are fine-print legalese and they're confusing. But despite that, 98.5 percent of the state's debtors try to navigate the process themselves, without any legal help. And they often end up paying more than they should.

Spencer Campbell spends much of his days walking the halls of Elk Ridge Middle School, checking breezeways for kids playing hooky, redirecting foot traffic between classes and checking on substitute teachers.

Campbell is one of two assistant principals at Elk Ridge, a school just south of Salt Lake City, Utah. It's his first year in the role and he looks the part. He's in his late 30s, sharply dressed, walks briskly and carries a walkie-talkie on his belt.

This time last year, Stephanie Johnson was miserable.

She was in her third year teaching special education at a junior high school in Lindon, Utah, about 40 minutes south of Salt Lake City.

On the outside it looked like she was doing great. Her classes ran smoothly, students loved her, parents loved her, but like many special education teachers, inside she felt as though she was drowning.

She said she thought about leaving all the time: "I don't know how to describe it, it's just so much work. I just feel like I cannot do it."

On a recent evening in Manhattan's Upper East Side, a group of women have gathered to chat. They're seated in the living room of a cozy one-bedroom apartment.

"I consider myself a cultural Mormon," says Christy Clegg, who grew up active in The Church of Jesus Christ of Latter-day Saints. "I don't attend regular church services on Sunday, but I very much identify with my Mormonism."

The group is called Feminist Home Evening. It's a play on words. Mormon families are encouraged to have Family Home Evening — a night at home — once a week.

Navigating airport security lines is a hassle, for most. Among the exceptions: passengers with TSA PreCheck stamped on their boarding pass.

They don't take off their shoes, they don't take out their laptops and they often clear security in just a few minutes. And now, there are a lot more of them.

In the past three months the number of applications for TSA PreCheck has more than doubled. Almost 16,000 people a day are now applying for PreCheck. That's a huge increase from less than 7,000 a day in March.
