Rarely in media stories will our vulnerability be front and centre, like our very own front-page headline in The Telegraph for the whole world to ponder than the warnings about health care. Yet, Mark Morri and Tim Blair have suitably warned of their recent health scares and the dangers at our own doorstep in regard to cardiac frailty. (See the doc and get your own heart unblocked, 16/5). With oxygen balance so easily tipped in the busiest organ of the body as it eagerly extracts more oxygen than any other, excessive exercise demand or stress can expose otherwise benign partial blockage with deadly consequences. Newly developed shortness of breath is surely as dire a symptom as chest pain as an augur of the imminent danger lying within. No effort should be spared in encouraging a healthy lifestyle and discouraging the bravado of those blinded by the overconfidence of self-perpetuated immortality. If not for themselves, men should be considerate of those around them to listen to the best advice. Mark Morri, thank you for sharing. Alan Sexton, North Parramatta. 17May2023.
