> ...age is a major factor in health Tangential, but: I read a fascinating book about ageing and death from a doctor who worked with such things. My big takeway, from a systems perspective, was that we generally don't die because of a single component-level failure but rather as a collective systematic overloads that push failure throughout the body until a component dies (and so do we). Age makes our lungs, arteries, heart, organs, and the rest of it work sub optimally. Poorer lung function forces our hearts to work harder. Poor heart function causes our lungs to work harder. An unusual shock like shovelling pushes all components, which push each other, which is a great way to trigger failure modes. This looks a lot like what we see in complex systems over time. Age is biological-debt :)
