michaelkeenan comments on Really Extreme Altruism

it should be possible to somehow quantify the benefit of donating a kidney, on some scale, at least.

From Wikipedia:

Kidney transplantation is a life-extending procedure.[24] The typical patient will live 10 to 15 years longer with a kidney transplant than if kept on dialysis.[25] The increase in longevity is greater for younger patients, but even 75-year-old recipients (the oldest group for which there is data) gain an average four more years of life. People generally have more energy, a less restricted diet, and fewer complications with a kidney transplant than if they stay on conventional dialysis.
