Surgeon James Guarrera harvests the damaged kidney of patient Adam Abernathy as part of a five-way organ transplant swap in New York, August 1, 2012. Abernathy's partner David Ferguson donated a kidney for transplant to a stranger while at the same time someone donated a kidney to Abernathy as part of chain of kidney donations that allowed five people to receive a transplanted kidney of a two day period. The health dangers for kidney donors is believed to be low. The risk of death from the surgery is 1 in 1,700, according to the National Kidney Foundation, and life expectancy is said to be unchanged with one kidney. Picture taken August 1, 2012.
