Um, what was i saying ..?

The average concentration span of a goldfish is about 1 second – after that, they just forget everything. Most goldfish spend all their time swimming around their bowl, being pleasantly surprised by all the new scenery.

Fortunately, we humans can concentrate for a little bit longer.

Clever fellas with big beards, worked out that your concentration span can be roughly worked out in minutes by adding one minute to the number of years old you are. This means that to get the most out of your brain, you need to work on one thing for a short burst, then have a break (and maybe a biscuit), and then ideally change some aspect of what you’re doing.

Drinking water

As we mentioned, fish aren’t too bright. You never see them talking with the Prime Minister, or trying to calculate how much a black hole weighs. But this is a little bit strange because they are always surrounded by water – and water is fantastically good at helping you to concentrate.

A bunch of Swiss boffins at the World Health Organsation, worked out that if we are 2% dehydrated, our ability to concentrate will fall by 20%. They reckon you should drink about two litres of water a day.

What all this means is that it is terrifically important to keep drinking lots of water if you want to be able to think clearly, or are about to try some quantum physics.
