As a kid in an ex-pat family, we once got stuck in civil unrest in Tanzania. The whole society collapsed overnight. No markets to buy food, no doctors in the hospitals, etc.
We were the lucky ones. Once a month we got from the company a big bag of food. I remember my mum saying that we had to be careful not to waste anything. Because there was always a chance that the next shipment could get delayed.
Once I saw the run on the supermarkets during the start of Covid 19 it all came back to me. I stepped in my car and bought 4 ha of good farmland with its own water source and little shelter. Insurance. Once bitten twice shy.
