@aeromax51 - thanks for very informative views.
Ultimately, judgments on what lockdown measures are needed must be based on the balance of risks of new variants and NHS being overwhelmed against damage to people's livelihoods, mental well being, education and physical health. Must be like a stab in the dark when so much is difficult or impossible to quantify.
However, IMO, we cannot hide away from CV19 forever, and we must get used to the fact that life is a risk, and not try to reduce or eliminate one risk (CV19) without full and thorough consideration of other risks.
