At a training facility in the middle of a desert in New Mexico, aspiring border patrol agent Stevany Shakare sprinted laps in 103-degree Fahrenheit weather as her instructors shouted at her to run faster.
"They weren't OK with it at first. It was the dangers of the job and being away from home. But eventually they realised this is what I wanted to do," Shakare said.
"My mom tells all of her friends, 'This is what my daughter is doing!' She's excited about it."
