Being an organ donor is all well and good, under a couple of conditions. One is that the donor should consent. Two is that the donor should already have died.
You'd think it would go without saying that the cause of death would be something other than removal of the organs to be transplanted, but apparently those inscrutable ChiComs see things differently. Especially if you are Falun Gong. Details here.
What the heck, they're just overgrown embryos anyway.
