There was a study earlier this year about how the average person has over 150 Facebook friends, but only four that they could count on in a crisis. Sometimes that's all you need though.

Denver resident Steve Kostiuk got diagnosed with lupus a while back. Then last year, his kidneys started failing.

He created a Facebook page called "Don't Need Pity, Just Need a Kidney." And he put an ad on the back of his SUV that listed his blood type and phone number. After a few months, he wasn't having any luck.

A guy by the name of Chad Logan saw the Facebook page. He and Steve played football together in high school, and hadn't seen each other in 20 years. Here's their team photo:

Chad wanted to help, because he saw that Steve had four kids who are all under the age of seven. So he got tested, and it turned out they were a match. He traveled to Denver last month from his home in Utah, and they saw each other for the first time in a couple decades.

The surgery happened five days later, everything went well, and they're both doing great now.
