A study of around 270,000 Americans after they had Covid-19 found that 37% of them had a symptom over three months later.

Some fraction of them may have developed the symptom from some other cause by coincidence, or already had it before catching Covid-19. It may be hard to distinguish those cases.

Angela Rayner, deputy leader of Labour, called Tories "scum". Now half the scum in Britain are distracting attention from their policies of cruelty by rebuking her crude language.

What Rayner said was totally justified, but the way Aneurin Bevan (also working class) said it was more effective and harder to attack superficially: "The Tories are lower than vermin." Be using a less common word to condemn them, and putting it inside a comparison, he made it sound incisive rather than crude.

Rayner should not even hint at apologizing, but rather than defending her insult, she should press the attack with varieties of brief but substantial condemnations.

This is an example of the sort of positive feedbacks that can lead to global heating worse than models have predicted.
