It is a popular mathematical experiment to try and work out just how fast Santa has to be to reach every house with a child in a single 24 hour period.

The calculations always end up with a significant fraction of the speed of light.

There then usually follow discussions about what the collateral damage from Santa's passing would be. And cargo limits, and so on.

All of these are wrong, and ignore another end-of-year tradition. The portrayal of the ending year as an old man.

Now that I've put these two traditions side-by-side, I think you can see what is really going on.

It is possible for one man to visit every house in a night, with no shock waves or any of that silliness. But it comes at a cost.

For that man, the night lasts many years, as he travels back in time after each visit. Even with time travel, he does not get much time to eat - so the snacks you leave out are essential to him surviving the night.

But he only just survives. By the end of the night he will have aged over forty years. And then he hands the reins of the time-travelling sleigh to a younger man, warning him of the cost.

Someone always answers the call, despite the cost, because there is always someone willing to sacrifice everything to bring joy and light, even just a little, even if only for a moment.

So leave the snacks, and, if you catch a glimpse of him, give him a bow of respect. He deserves it.
