I've had my knowledge of mental health highlighted. Weirdly enough, my unwell daughter has found strength and is pulling herself together. ( Managed to get her out of hospital just as the Covid cases in there were starting to sky rocket.) My 19 yr old though is struggling and she's always seemed far more mature than her years. She works for the probation service so has to work still - someone's gotta keep an eye on the "ne'r do wells" that have been released. It's interesting seeing how the situation is affecting friends and family from a mental point of view.
I've also learnt to trust my instinct in the early stages of an event more. I put off a few purchases that I now can't get easily. Also while Jansman as you often rightly say, cash is king, in this case contact less payment is the preferred way atm while the system is still running. (We may yet need barter and cash, who knows.) My mum has had to learn to do contactless as she's always resisted it up till now. She doesn't online banking and leaves it to my dad, so god forbid should something happen to him, she'd be in a pickle.
