Where in the Constitution is There a Guarantee for Health Care?

Consider the state of medicine in the late 1700s. The Founding Fathers may have been smart guys, but why would they have anything meaningful to say about health care? It had only been 25 years since barbers were legitimately doing amputations. Physicians still balanced humors. Medical licensing did not happen until 25 to 50 years later. The Constitution is a living document because they KNEW it wasn't perfect.
