'It's Been Surreal': Hundreds Line Up to Donate Blood to Orlando Shooting Victims

Here's a story that will warm your heart.

A Utah man donated his kidney to a friend from high school who he hadn't seen in years.

Chad Logan and Steve Kostiuk, who played football together at Jefferson High School in Edgewater, Colorado, lost touch after high school and hadn't spoken in more than 20 years.

During those years, Kostiuk was diagnozed with lupus, and his kidneys began to fail late last year.

He needed a kidney, but his blood type ruled out any immediate family.

He started a campaign to find a donor, including advertisements on his car and on social media.

When Logan became aware of his old friend's predicament, he offered his own kidney. Luckily, he was a perfect match.

The lifesaving surgery took place at Presbyterian/St. Luke’s Medical Center in Denver last month.

"I feel absolutely fantastic," Kostiuk said on "Fox and Friends Weekend" this morning. "It's a whole new life for me."

Logan explained that when he read Kostiuk's story online - particularly the detail that he has four children under the age of seven - he knew that he simply had to help his former teammate.

"When they called me and told me that Chad was the donor, I broke down in tears," Kostiuk said. "He's changing the lives of my family and my friends and my colleagues."
