A Good Samaritan kidney donation by a California man began a progression of kidney retrievals and transplants, as 30 donors gave their organs to 30 strangers on behalf of their loved ones.
This remarkable story (of 2012) was captured in a multimedia story by the New York times.
It includes 3 videos, the 2nd of which (about pair 19) shows the emotion of waiting for the right donor to come forward and how it can be a start-stop process. It also explains the concept of paired donation and the huge impact it can have in improving the actual recipients transplant outcome.
All it took was this one altuistic donor to create a massive chain of transplants to benefit 30 recipients. As the Americans would say - "Way to go!"
