Remember why we have lockdown - to protect the NHS, not you.
The problem with this flu is that it is more contagious, it spreads rapidly given the chance. Without measures to slow spread, the NHS might get overwhelmed, people might be unable to get into a hospital.
So @Wannabangbang , if people don't follow lockdown policy, the epidemic won't last longer, it'll be over sooner because more people get infected sooner. The problem is whether more people die because the hospitals get full?
IMO govt has it wrong to enforce excessive lockdown such as no travel in cars, no going to parks or walks in the countryside, no going to non-essential work even if you work alone, etc. Most people, and especially the vulnerable, will voluntarily follow distancing, sanitary procedures, minimising contacts and even self isolation. The few who don't will make little difference. It's what the majority do that affects the statistics.
I think the reason for the draconian measures and dire warnings is to scare the bejeebers out of us, so that we won't question anything they do and afterwards will be grateful for their strong response, however bad things are afterwards.
Lockdown won't go on for ever. Printing money hits even politicians and their own standard of living will follow ours down. Deaths caused by lack of medical treatment for non-covid conditions and by suicides will start to outstrip covid related deaths. They'll find out that all those non-essential workers are not so non-essential. Non-selective lockdown will end.
But whether or not there is a vaccine it will become just another flu. Perhaps one of the more virulent ones, but not so different from the ones we get every year. We* will live with it and die of it, as we do with the other flus, which cause 30,000 deaths a year (out of the half million or so people who die each year.)
*Well, you will. I'm old enough not to have to worry about the future. I'm just sorry that the govt has sacrificed so much of your futures to try to keep a few old codgers like me going for a few more years (or maybe months, or even days.)
