You may believe that peeing doesn't require much thought, but it turns out there's actually a bit more to consider when it comes to emptying your bladder.
Ah, the peace and quiet of being able to go and sit down and have a wee, staring into the abyss of the bathroom, allowing your mind to temporarily wander, taking in the peace and quiet before having to drag yourself back into reality - no, just me?
Alas, you may need to be concentrating a bit harder the next time you go to relieve yourself of bodily fluids but thankfully, scientists have come up with a '21 second rule' which is pretty easy to follow.

A group of mechanical engineering students at the Georgia Institute of Technology conducted a study into what the length of our pees says about our health.
For the study, the team of researchers analyzed high-speed videos of animals of all different sizes peeing and coined the term 'The Law of Urination'.
It found that animals that are over three kilograms (6.6 pounds) empty their bladders over a period of around 21 seconds while smaller animals - i.e. rats - took just a fraction of a second to empty their bladders.
The researchers were able to confirm pee duration is ultimately not just to do with bladder pressure - it's related to gravity as well, IFL Science explains.
Published back in 2014, the paper states: "How can bladders of both 0.5kg and 100kg be emptied in nearly the same duration? Larger animals have longer urethras, and so greater gravitational force driving flow.
"These long urethras increase the flow rate of larger animals, enabling them to perform the feat of emptying their substantial bladders over approximately the same duration."
And the study ultimately found out the ideal length of time it should take humans to wee too.
So, next time you sit down for a number one, get your stopwatch at the ready and see if you make the time of around 21 seconds.
If you end up falling short or exceeding the mark, it could be a sign you're visiting the loo too often - I see you those of you trying to avoid work - or not enough - workaholics, take note.
If you pee too often, it could lead to you having what's known as an 'overactive bladder' while holding in your pee for too long could cause you develop a UTI - and believe me, you want to avoid those like the plague.
There's also an increased risk of kidney disease if you're an infrequent toilet-goer alongside your bladder becoming enlarged or even rupturing.
So, drink up and make sure to embrace the toilet breaks.
