And each year, Christmas produces some new quirk to test those survival skills.
This year it is Christmas Car Park Rage, which has been identified by those who study these things as a new and dangerous phenomenon.
Apparently, as the nation goes shopping crazy and store car parks get fuller and fuller, the race for a car park hits a new intensity. Collisions, bangs and scrapes become more common, and anger levels rise accordingly.
Having come out of the supermarket to find a fresh dent in my bodywork, I can attest to the problem. I could have fallen victim to Christmas Car Park Rage, but then I remembered this important seasonal message — "Stay calm out there, folks".
Still, not all new Xmas phenomena are bad.
Here's the bright side — New Zealand now has its first ever Secret Santa for pets.
The initiative is being run by Inspector Spot, NZ's first Certified Pet Detective and it's taken off big time.
So forget Jacinda Ardern and her plea for bottled relaxation and sleep, and wrap up a tin of Whiskas or a nice juicy bone and let a faithful pet savour the true spirit of Christmas.
