I get the impression that hardly a day goes by when we aren't given something to worry about.
Going back, there was WW1 followed by a flu epidemic. Then there was the depression and hunger marches and WW2. After the real war there was the 'Cold war' and the threat of extermination, but we got through that (only just) and had to think of more things to worry about.
We have recessions, depressions, energy crisis, Obesity and Diabetes "epidemics" - neither of which are epidemics, and of course Global warming and declaring a "Climate emergency".
Do we actually need something to worry about all the time? Are we never just happy that things occasionally go OK?
Well, I'm declaring a Walnut oil crisis. Looked everywhere for it without success. And please don't suggest Waitrose as the nearest one is 175 miles away.
