Some time ago, I was introduced, by The Hitchhiker’s Guide to the Galaxy Wiki, to the following explanation of the choice of the number 42 as the ‘Ultimate Answer to Life, the Universe, and Everything’. It is from the horse’s mouth:
The answer to this is very simple. It was a joke. It had to be a number, an
Douglas Adams, 1952–2001 (alt.fan.douglas-adams 03Nov1993)
ordinary, smallish number, and I chose that one. Binary representations,
base thirteen, Tibetan monks are all complete nonsense. I sat at my desk,
stared into the garden and thought ’42 will do’ I typed it out. End of story.
Since then, my doubts have been rekindled by this assertion from ‘the voice of the audiobook’, a man who knew DNA well:
Douglas told me in the strictest confidence exactly why 42. The answer is fascinating, extraordinary and, when you think hard about it, completely obvious. Nonetheless amazing for that. Remarkable really. But sadly I cannot share it with anyone and the secret must go with me to the grave. Pity, because it explains so much beyond the books. It really does explain the secret of life, the universe, and everything.
Stephen Fry (quote from BBC News Magazine 07Mar2008)
In August 2021, this comment appeared on THHGTTG Wiki (lightly edited for clarity):
I wish I could say I found the answer, but alas someone else figured it out and I thought I would pass it on. Simply put, the answer to the life, the universe, and everything, is a Hot Shower. 42 Celcius is ~108 Fahrenheit. If you want a hot shower, you set the water heater/ boiler temperature near this number. Douglas Adams lived in England, so it makes sense he would use Celsius. Think about all the connections in the book to towels… yet never for one of their main purposes, drying off.
If you were a hitchhiker stuck in a Vogon cargo hold… wouldn’t the first thing you want when you get to the Heart of Gold, be a hot shower? I mean you have your towel ready, right? But no, Arthur perpetually in his robe, never showering, always stumbling around. All he needs is a hot shower! Ideally with Trillian!
Where do people do some of their best thinking?
I’m sure there are more connections […]. Thank you Douglas Adams, you are a true genius. Your secret lasted a long time… but it’s time to tell the world.
WonkoTheInsane, The real meaning of 42 22Aug2021
Wonko’s statement isn’t quite right: he suggests that there’s never any reference to ‘drying off’, but there is at least one:
A towel is just about the most massively useful thing an interstellar hitchhiker can carry. Partly because it has great practical value. You can […] wave your towel in emergencies as a distress signal, and of course, you can dry yourself off with it if it still seems to be clean enough.
The Hitchhiker’s Guide to the Galaxy
Nevertheless, This Hot Shower Hypothesis does, I think, have merit. If the Answer is 42°C, the Ultimate Question becomes: “What is the ideal temperature for a hot shower?”
The truth is: Douglas was an inveterate trickster. You only have to take one look at the impish expression on his face in the picture below (which I always keep nearby for when I need a good chuckle) to realise that. I feel sure he would be tickled to bits that his prank has persisted so long.
“There’s a frood who really knows where his towel is.”

Towel Day 2023
Note: the clock is calibrated according to 10:10:10 UTC
as that, to me, is the best time for this planetary event.
PS @Rusty:
I was planning to expand this along the ‘Weak > Medium > Strong’
lines you suggested (a while ago now), but this draft has
idled in limbo too long; and with just 42 days until
this year’s Towel Day I find that my supply
of round tuits is in serious need
of replenishment.
Sorry!
