Aye Ian,
They don't appear to be "ravings" and whether you are "fat and old", I cannot assess, end of.
Mmmmm! The lockdown and economics, resulting in anxiety. I agree, but I am in a fortunate position not to be couped up in close proximity to other people and can still support my local essential businesses.
As for the virus, the 'developed'

world has 'forgotten' about viral infections and their ability to mutate. Has anybody made a review of the Spanish flu pandemic? A summary pulled from a publication from 2010 "The Spanish flu pandemic of 1918, the deadliest in history, infected an estimated 500 million people worldwide—about one-third of the planet’s population—and killed an estimated 20 million to 50 million victims" :

"Economics", is THE problem!

Theorising by educated individuals, wishing to speculate and forecast on what things might be worth. All based upon the underlying premis that the resources upon which this theory is based are infinite. I disagree; the resources are finite and not readily available. Whilst the individuals maybe educated, they are not necessarily savvy or compassionate.
Like overcrowded mice and rat populations our time will come for a population crash. How, where, when, I have no idea.
As the late great Dave Allen said "And may your God go with you!". We make our choices and then have to live with them, all spiced up by mutation and chaos!
Go canny and enjoy your riding.
Good health, Bill
