I don't agree with this lockdown but then I'm basing this on my own experiences with it.
DH, I and 2 DC all had it. I was quite sick but not enough for hospital.
Aunty, uncle, their son and DIL, 2 GC and other set of GP's all had it. Aunt is 70, smoker and asthmatic. She was on oxygen and survived.
Friend had it, got better.
Other friend, DH and 4 DC had it. She had long COVID. She is very, very overweight.
GP, was in end of life care, caught COVID in hospital and died. It's 3rd on her death cert.
Other elderly relative, amputee, has dementia, caught in care home, is 80, went to hospital and is over it.
So, whilst I appreciate it does kill a very small % if young, fit people, all the people I know who have had it have got better with the exception of 1 who had 3-6 months to live. COVID put extra pressure on their failing heart, it wasn't the COVID that ended it.
Do I think another lockdown is a good idea? No I don't. Based on my own experiences I'd rather get it than screw up my kids futures and lose our jobs, homes and quality of life.
