Colleen, no I haven't, but because of my age, the Veterans Administration said I would not be a good candidate.I don't expect to be a possible donor so I truly believe our young doctors can benefit by doing the actual transplant. When I say any type liver transplant, I mean "ANY"including animal donors and mechanical devices.My wife and I have throughly discussed this and she is in total agreement.Thanks for anything you can do to bring this to fruition.
