I would not give a kidney to a dying relative

Having one kidney isn't permanently crippling your health. It's a serious operation, though, to be fair. Do you know what is involved in giving bone marrow, by the way? If you do, and you'd volunteer for this, I'm amazed you'd stop at a kidney.

I would shart for someone though

You're lucky that you even have the option to donate your kidneys. I'm on a lot of medication so I'm afraid that my kidneys are "tainted" and I can't donate one if someone in my family needed it. That actually makes me really sad, like to-the-point-of-tears sad, because I view giving up one of your organs to someone in need as one of the ultimate sacrifices, short of giving up your own life. I would be more than willing to donate my kidney to someone in need, even if they were a complete stranger.

I agree with dappled

Not to be shallow, but I don't know how I would handle someone asking me to deliberately scar my body.

Angel, lighten up. Most of our family members are old enough now; it's not the end of the world (ours) if they die.

I wouldn't either. I'd give it to my boyfriend if he needed it, otherwise no. I don't believe in pushing life, if you die or are dying, I'd prefer you just deal. I know it's hard, but if something failed, you're either mistreating it or your bodies not working- in which case why risk pushing your other organs to the limit?

So you'd rather see them dead?

I heard giving bone marrow is excrutiatingly painful.

I could say no to most family members but if my mom or bf needed a kidney they could have it.

It's your kidney. Nobody should force you to cut it out.
...But I can't imagine saying "no" to a loved one.

I would only give it to my girlfriend.
