Looks like the opinion of most people - whether experts or not - is that Covid19 is not going away, either with or without booster vaccinations.
Add to this that opinions are divided on whether new variants will be more transmissible with greater severity, but let's err on the side of caution and say they will be.
We now have a scenario where Covid19 is progressing steadily (or rapidly) into a highly contagious killer that cannot be controlled.
Once the death rate surpasses the birth rate, the human population is on a downward spiral to oblivion - the much favoured worst case scenario.
We're doomed, so the only advice I have to offer is borrow as much money as you can and spend it with glee, quit work and do whatever takes your fancy, don't bother mowing the lawn, decorating, or building that new kitchen extension, binge watch all the TV you've been putting off, and drink/eat anythingl you like . . there is no tomorrow
