It’s one of the biggest mysteries of our time, and it has just been solved by a penguin.
The secret to a lasting, happy relationship is… time off for good behaviour.
According to new research, penguins are faithful to their partners, making them something of an anomaly in the animal kingdom.
In not unrelated news, every winter the emperor penguin females travel more than 600 miles north in search of food.
So the key to domestic bliss? Splitting up for the winter. Not a coincidence that this also means penguins avoid all rows about when to put the central heating on.
So now that’s sorted at last. Wonder if there are there any other relationship tips we can pick up from animals?
