See, Cheney has had a heart condition for many years now and has suffered heart failure. If this were the 1960's, the man would almost certainly be dead right now because the effects of all of this has been to render his heart too weak to pump blood throughout his body quickly and effectively enough to nourish it. So he is now fitted with a remarkable device:
His new mechanical pump, a partial artificial heart known as a ventricular assist device, leaves patients without a pulse because it pushes blood continuously instead of mimicking the heart’s own beat. Most pulse-less patients feel nothing unusual, but the devices do pose significant risks of infection. They are implanted as a last resort either for permanent use or as a bridge to transplant until a donor heart can be found. Mr. Cheney, who has participated in some of the nation’s toughest decisions for decades, now faces a crucial one of his own: whether to seek a full heart transplant. ... With most patients, a power line emerges about waist level and connects to a controller, a minicomputer that plugs into a pair of one-and-a-half-pound, 12-volt batteries. Patients wear a black mesh vest over their clothing that holds the controller and batteries.He will never be able to take a shower again, unless he has a heart transplant, because of all that electronic equipment. A sponge bath will do for hygiene and odor control, which sucks, although if it came down to a choice between a life of only sponge baths and dying, I'd take the sponge any day.
The point here is not to do a pre-mortem on the man or his politics. Even if you detested the man, thought he was corrupt and evil, and couldn't wait for him to get out of power, that's not a reason to wish him death or wish that his family have to go through grief for him. And for now, they won't. No, the point here is to marvel that despite suffering repeated heart failures, modern technology has a way to keep him alive.
"But Cheney is really, really rich," you say, "and someone like you or me could never afford this miraculous technology if we had the same condition he did." Well, right now that's true. And yes, it is fortunate for Cheney that he is personally wealthy and so the cost of all this technology is well within his grasp. But you're not taking a long view to lodge that sort of protest. Yes, it's always the wealthy who get this sort of stuff first. They buy the technology at a premium price, which enables the developers of that technology to both recoup their startup costs and thus offer it for sale in the future at a lower price, and it creates an incentive for even more science, research, and technology to be developed in the future.
This is why I like both science and economics so much. They save lives.
