Most people want to live long and they want to live well. Quantity of life is experienced through the lens of quality – surviving is not enough without thriving. And the whole idea of quality only exists within the broader reality of the scarcity and uncertainty that is inherent in life. We can acknowledge this truth without allowing it to paralyze us. We can live with the knowledge that life is finite and that its end – in both timing and circumstances – is uncertain. Still, living in constant fear of illness and death can wreck an otherwise good span of years.
