While looking into the age limit for living liver donors a few months ago I discovered the age limit for living kidney donors at most transplant centers was 65. I just recently revisited the topic and found they have raised the age limit to 69 for living kidney donors. Could be due to advanced technology which may be reducing risk factors involved. My son recently had a cholecystectomy where they used the robot. Went through his belly button. Six weeks later can't even tell he had surgery.
