How are these 60 people linked? Well, see, after Rick Ruzzamenti, upper left, decided to donate his kidney, it set off a chain of kidney donation that led to 30 people getting 30 kidneys from people they didn’t know. It was the ultimate case of paying it forward. Ruzzamenti’s selfless gesture inspired the loved ones of those receiving kidneys — who weren’t matches with their relatives — to commit similar acts of selflessness. The result, what the National Kidney Registry calls Chain 124, led to people in 11 states getting a new lease on life.
