It is amazing how the virus mutates and defeats all our best efforts to keep it under control, we are told it does this just by chance.
Chance means it is possible that a mutation could occur in a really small group of infected people but is more likely in a larger group. In other words the larger the pool the greater the chance of a new successful variant.
In the UK, the successful wartime government was formed from a wide pool of men and women from all walks of life. Some were Lords of the Realm and others were ordinary people, they were chosen for their expertise rather than who they knew or who they were related to. So, there was a good chance of picking the right person from this very large pool.
Compare that with the tiny pool we have now, many of them are actually related or just chancers in the know, and able to bid for PPE contracts for which they had little expertise and ignoring firms that were ready to supply.
Imagine if we had this lot looking after us in those terrible war years.
As always, chance has played its part and now we have our very own UK Covid variant, not a thing to be proud of though.
