Results: Extreme Acts of Kindness

She walked away, and Jon quickly felt a wave of regret. He got out of his car to look for her, but she was gone. Feeling terrible, he vowed to be kinder next time a stranger needed help. Have you ever regretted saying or doing something - that you were unable to fix later?

A few weeks later, in the spring of 2015, he saw his opportunity when someone on a Pittsburgh Reddit group needed a hand installing a television antenna. Potter, who is handy, did it for no charge and felt great about it. Then someone on the same Reddit group asked for a cat sitter and he jumped at the chance. Have you ever done a favor for someone and experienced the joy from helping your fellow man (or woman)?

"It snowballed from there," said Potter, 29. "I decided that for the next year, if anyone asks me for help, as long as it's legal and as long as it won't harm anyone else, I'd do it. It sounds ridiculous, but I did it." Would you like to do something similar - say yes to everyone that needs help with something - as long as it is possible for you to help them out?

Potter upped the ante on his generosity last week, donating a kidney to a stranger after seeing on Reddit that a Pittsburgh father of two was in need of a transplant. The man, Michael Moore, 57, had put out a plea on social media through his daughters. Do you know of anyone in need of an organ donation - or any similar medical procedure - that turned to social media to try to find someone to help?

Never one to back down from a good deed, Jon did some research and found out he could live a long and healthy life with one kidney. Then he got tested and learned he was a perfect match for the man in need. He had to do some convincing to get his wife of about year, Rachel Adler, on board, but she came around to the idea. The surgery was Aug. 13, and both men are in recovery and doing great. Would you consider donating a kidney to a stranger while you are still alive?
