We're about to have a very interesting week in the UK. School and work is going back and at least 1 in 25 people currently have Covid. Probably the real number is higher than that. Will there be mass staff shortages across education, health care, retail and logistics? We're about to find out.

Other unknowns: How often will people get reinfected? How much protection from the boosters will wear off quickly? Is Covid also mutating in animals, and will variants blind side us that way? How long will it be before the next variant? Will we ever see the end of this?

All in all this is a shit show.
