For many, helping a sick family member is something they would happily do. But how far would you be willing to go to help a complete stranger?
Theresa Laher is a teacher at University High School. She says a speaker gave a talk to her health class about organ donation, and something he said never left her mind.
"I kind of think we're born with two kidneys so we can give one away, and he made a joke about it, but that was the message for me," she said.
She decided to become an altruistic donor, giving her kidney to a complete stranger three months ago. This month she met the recipient, Albert Garza, for the first time.
"I can tell her thank you for the rest of my life, but I'll never be able to pay back what she's done for me." Garza said. "She gave me back my life, you know, I just can't explain it."
Garza no longer needs daily 10-hour dialysis sessions. Now he can hunt, fish and be the husband and father he's only dreamed of being and that's exactly the change Theresa wanted to be in someone's life.
"You know in my life I want to be a person who makes a difference. But, to be able to see that while I'm living is great. Because we can all be organ donors when we're deceased, but to be able to do that when we're alive is a beautiful thing," she said.
