Oklahoma highway patrolman Clinton Riggs was a student at the Northwestern University Traffic Institute, now the Center for Public Safety, in 1939 when he created the yield sign as a class assignment. The original yield sign was keystone shaped and read, “Yield Right of Way” in black letters on a bright, yellow background. Yellow was used because reflective material was not yet available and it was the most visible color at night.

Riggs’ goal was to improve public safety and determine liability in an accident.  In 1950, as a member of the Tulsa Police Department, Riggs placed the first yield sign at the most dangerous intersection in the city. Within a year, the number of accidents fell to zero. By 1954, the Manual on Uniform Traffic Control Devices added the yield sign to similar right-of-way intersections. Yield signs soon appeared at intersections across the country, with the keystone shape being replaced with an upside-down triangle with black lettering and a border, but the sign remained yellow. Over time, the signs began only saying “yield.”

Jasen Bracy always wanted to play football, but retinal cancer he developed as a toddler took his eyesight by the time he was age 7. How could he play a fast-paced contact sport like football if he couldn't see?

This was the question before him. Yet young Jasen would not be dissauded. As he got older, he began calling around to different youth leagues to see if there were any teams that would take a chance on a kid who was sold out to following and relying on the guidance and direction of others to make his dreams come true. He found just such a team in the Modesto Raiders.

"The way he was on the phone, I just said, 'Come on we'll figure it out,'" coach David Nichols told CBS News.

Jasen started out as a running back, but soon advanced to ... wait for it ... quarterback!

"It's all memory," Jasen said. "It's all about having trust in the player, the receiver and the team. I have to trust them 100%.

Upworthy reports:

Bracy's teammates guide him into position on the field and his dad coaches him from the sidelines using a walkie-talkie that transmits to his helmet. "After the play starts, I may tell him, 'Hey, run to your right, let's get upfield,' or 'Watch out, somebody's coming to hit you,'" Bracy Sr. said.

All that trust, all that deep leaning into guidance and direction seems to have paid off. Not long after, Bracy led the Raiders to a 33-6 win.

My wife an I took a vacation to Boston. We love to travel when we can and we tend to try to see everything a person can possibly see. On our first day in Boston we walked the Freedom Trail. We could have taken a 2 hour tour (with a tour guide!), but we wanted to see it all. We wanted to do it our way. We took the better part of the morning and afternoon seeing it all. I'm not sure how far we walked, but it was miles.  Near the end of the Freedom Trail you find the Bunker Hill monument.  It's 294 steps up the 221 foot tall monument. That's about 22 stories after walking all day. You also have to come down the steps.

Once we got outside, my legs were so weak that I was wobbly.  I had to stop and gather myself, but it was only about 4pm and we had the USS Constitution, the Boston Public Library, and Cheers to see that day.  So we kept going.  In the middle of the evening tour of the Boston Library, I realized that I couldn't walk down any of the steps.  I was holding onto rails and "floating down."  It was the same trying to go down the stairs to the subway. I was beginning to wonder if I was going to be injured for the rest of our trip!
