Every comment on here is just that an opinion, it's not based on scientific knowledge, nor, as far as I can see, for the greater good, but very much for individual comfort. So, I'm going to add my opinion.....
Personally, and as someone isolating so as not to place a burden on an already stretched NHS, I believe that the lockdown needs to continue beyond the next 3 weeks. Everything that I have read suggests that if lock down is lifted at this stage, there will be a second wave of infection very quickly after.
Have none of you seen our NHS and other essential workers, and how exhausted they are? Before introducing a second wave of high infection levels, they need to catch their breath, and build up their strength. Meanwhile, the govt., AND business owners, need to put into place a realistic strategy of return, and I suspect that this will include permanent changes to the way in which we work.
Our jobs meanwhile, is to follow instructions to the letter, and allow those IN THE KNOW, to make their decisions based on facts.
