Bullshit; it's not a medical failure any more than my car eventually breaking down and needing to be replaced is an engineering failure, or my house rotting away due to erosion. The second law of thermodynamics is a fundamental constraint on the universe, not a failure on our part to circumvent it.
Both your car breaking down and your house rotting away can be more or less easily prevented, if you are willing to pay. If we were unable to replace a rusted exhaust or fix a leaky roof, that would be an engineering failure.
