Kidney Fern New Zealand.

Cornell professor Ron Ehrenberg needed a kidney. For five years, he and his wife searched for a donor to treat his end-stage renal disease. As hope faded, Ehrenberg began dialysis.

Behind the scenes, co-worker Adam Seth Litwin knew he was a match but did not qualify for the surgery because of his weight and health.

For two years, Litwin quietly exercised, lost 25 pounds, and improved his diet and blood sugar so he could donate a kidney.

Today, Ehrenberg has a new kidney and is enjoying retirement with his family.
