When I am dead however, they can take my kidneys, heart, lungs, liver and whatever else that is salvageable and give them to whoever needs them (assuming I die in the right circumstances that this is possible).
Given compatibility concerns, it's probably safer for your family member for you to donate than not.
One kidney failed after 3 years, the other kidney is still going strong. That person she saved has gone on to have 17 years of good health and counting, our family get’s anonymous letters letting us know the kidney is still going strong. It’s kind of nice.
If I don’t get to donate my organs to save lives, I’ll still donate them to science. I was Born with two kidneys and I like to think wanting to keep them for myself isn’t being greedy. If someone I love needs a kidney, I’ll donate to either them, or someone else so they can hopefully receive a kidney quicker, but otherwise, I have no desire to have a major surgical procedure, recovery etc. maybe I’m selfish, but I’ll at least be honest about it.
