About a month ago, I took a trip to the Cleveland Clinic. I met a lot of great people, but one stood out—even if he needed to stand on a chair to do it. Parker Frey is 10 years old. He’s struggled with severe asthma all his life. His mom said despite his challenges, Parker’s a tough, active kid—and a stellar hockey player.

But sometimes, she says, the air is too dangerous for him to play outside. In the United States of America, no parent should ever have that worry.
