Dealing with winter. I live in the rural upper Midwest, where winter can hit -20 with whiteout blizzards, week-long power outages, and car-burying snowdrifts. I’ve seen too many people move here from warmer places and think “I guess I’ll buy a warmer coat and a snow shovel”, rather than “I should have a backup generator, a backup heat source, a few barrels of spare fuel, a month’s worth of stockpiled food, and at least two different pieces of heavy snow-moving machinery tested to be in good working order”.
I find it interesting that even the Catholic Church has implemented an age limit for decision makers. New Popes (lifetime appointment) are chosen by the Cardinals (lifetime appointment), but only Cardinals under 80 are eligible to vote. https://en.wikipedia.org/wiki/Ingravescentem_aetatem
