I do not support another lockdown and I am not hard of thinking as the OP so charmingly put it. Quite the opposite, I have done nothing but arm myself with data and read stats constantly over the last few months.
So we lock down again and then what? Covid is going nowhere and we have no guarantee of a vaccine that will work - especially as vaccines generally have lower efficacy in older people, who are the ones overwhelmingly dying of Covid. As soon as you lift lockdown the cycle begins again.
Another lockdown will do more harm than good because you cannot stop people dying. They either die of Covid or they die because we stopped giving a shit about any other illness, or the economy, or education, or people's mental health. Hobson's choice OP because you don't get to save everyone. Personally I will choose the young over the elderly as they have a much longer future ahead of them. And you know what, every single elderly person in my life has said the same thing. My in-laws are mid 80's in not great health. We have done everything we can to keep them safe but would they put themselves ahead of their 19 year old grandchildren's future? Absolutely not.
Numbers are going up right now and it is concerning that there has been an uptick in hospital admissions but you need to remember that, even at the peak, we were nowhere near overwhelmed in the NHS. When this started we had 5900 ICU beds in the country and at the peak there were just over 3000 used. Since then we have added capacity and developed several treatments that have made a considerable difference.
Also, remember that it is not cases going up but positive PCR tests. Some of those will lead to cases but many won't. We all carry viruses all the time and sometimes they make us sick but often they don't. Covid is the first time we are calling a positive test a case and it is simply untrue.
My prediction for this post? You'll ignore every single rational point I've made and instead call me a granny killer because I have dared to suggest that, when deciding who lives or dies, I choose the heart attack victims, delayed cancer diagnoses, stroke treatments etc etc etc. By the way, that is precisely how the NHS and NICE operate normally making healthcare decisions for the majority not the minority and using QALY as an objective tool because as humans it's hard to make a rational and not emotional assessment.
