I'm living with heart failure. I have 20-30 years before I'll need a transplant, if I live a perfect lifestyle and keep my other health issues under control. Due to my other health issues, I am not a good candidate for a human heart transplant. It's not that a human heart transplant would fail, but that when I'd be placed against others on the list for a new heart, my other health issues would reduce my priority such that there is always someone with higher priority to receive a heart, up until the point in which I'm no longer healthy enough to receive a transplant. There are far too few human hearts, and far too many people who need one. All that the transplant boards can do is give hearts to those with the greatest momentary need, with the best chance of surviving.

Xenotransplantation is one of the life lines I'm counting on. I'm hoping that, by the time I need it, the issues that we currently have will be worked out. I have zero ethical issues with breeding and eventually culling pigs in order to save human lives. I hope that there will be other, better, breakthroughs by then, but if not, the best I can hope for is that the pigs are raised in a sterile and enriching environment, and that the only bad day they have is their last day.
