Yes. And I volunteer plasma every 2 weeks. Up to 25 donations in a weeks time.
Organ donation is the last honorable / good thing you can do for the world after you've left. You'll be forgotten soon after dying, so might as well make it worth something
For everyone who says they're not comfortable with the idea of receiving, when you're in a desperate situation thinking of mortality, I'm sure you'll suddenly change your mind.
Even small things like when I was in Nepal, I've seen people turn desperate. When it comes down life or death, what choice do you have?
