Yes and no, Mr Red.

But after a year's testing and trickle feeding out the vaccine to the most deserving in society, assuming the world can produce enough effective vaccine in a year. Do you have any idea of the logistics involved? Do we have enough chickens to make all the eggs? And if we do, less eggs for eating & up goes the price of eggs on the retail market.

Brexshit will be a reality and the price of eggs (et al) will be rising as a result. And which will be the more scary?
1) The UK out on a limb with few deals in place and new systems in place like customs deflating the excitement of foreign travel.
2) Or Travel abroad pretty scary on its own, with uncertainty if getting home un-plannable ahead and how much quarantine necessary on return. Not to mention the long term affects of surviving the virus!

My point was: Brexshit will be a lesser concern by comparison, and it can be endured, and enduring it will be. History tells us. If we listen.
