Ferfal (his nom de blog: his real name is Fernando Aguirre), who blogs at Survival In Argentina, also has a YouTube channel where he does regular podcasts and short "lessons learned" videos. Here's one he posted yesterday, analyzing why many so-called "preppers" were caught short by the sudden arrival of the coronavirus pandemic. He makes some good points, and highlights valuable lessons we can all learn.
Interesting and thought-provoking. He has many other videos on his channel, which will repay your attention.
