Random observations on fitness and COVID-19

A surprising degree of core strength can be acquired by maintaining correct posture at all times while sitting, standing, walking and driving. This is easy to do, once sufficient muscle control has been achieved. Achieving sufficient muscle control, and internalising it mentally to the point where it becomes automatic, appears to take years. I have therefore filed it as one of those things that are simple, but not easy.

A friend of mine said (in my view very sapiently) that COVID-19 is an ongoing marshmallow test for the whole world, and it is interesting to observe how different societies are doing at it. I am aware that the real marshmallow test actually measures something different from what was originally thought, but in the case of COVID-19, wealth and security have not in fact been shown to correlate with greater societal capacity to deal with a pandemic.
