https://www.bbc.co.uk/sounds/play/p02c6s41 Keith lecturer, a world class healthcare professor recounts story of his own son…

He found the one leading surgeon in the world, who figured out how to perform a certain procedure. Everyone else in the world is lacking that knowledge.

Patients need to know more about their doctors and the treatment options. Singapore patients are “lazy” and too “trusting”.

Now I feel there are serious limitations (what Dr Atul refers to as ignorance + ineptitude) in the current knowledge of the human body. For example, how BMI interacts with heart health, longevity etc.

Luckily for my physiological “system”, the effect of diet on BMI is more predictable (not “better understood”) than in other people’s bodies. Still there are many uncertainties and mysterious how my long term BMI will evolve.
