Eating is more vital to living than anything else. So too is shelter. And both are on a day-to-day basis, not ocassional, like health care. If you want to interpret "Rights...Life" as people being entitled to free health care, everyone should get free food and housing. And the DoI conveniently failed to address how slaves fit under "all men are created equal," so it can't be held-up as some paragon for morality.
And if ObamaCare gets passed, a lot of people will have their life and death chosen for them. In England, you cannot receive dialysis after age 55, as just one example. How else are you going to control health care costs, especially if you're paying for everyone now?
