May I have your attention, please? I'll try and be quick, as I probably only have about 47 seconds before your mind starts wandering. That, according to psychologist Dr Gloria Mark, from the University of California, Irvine, is now our average attention span, based on her latest study of people's use of screens in the workplace.
When her team conducted a similar study back in 2004 (before anyone had a smartphone and there was no such thing as TikTok) we could focus for two and a half minutes before wanting to switch to something new.
Of course, these figures have their limits. Your declining concentration when grinding out a report may not mean your overall focus levels are collapsing.
After all, if you were sent a long message about some juicy gossip, you'd likely be able to give this your full focus for the required time.
As other psychologists have argued, your concentration can vary so much, that the very idea of an 'average' attention span is almost meaningless.
Because of this, there isn't even a scientific consensus on how to measure focus.
Nevertheless, it's likely you feel like yours is dwindling. As one recent survey from the Centre for Attention Studies at King's College London suggests, nearly half the population now feel as if theirs is worse than it was. With the ever-present pull of our emails (we check them 77 times a day, according to Mark's research) and social media (up to 237 times a day for some), it's easy to see why.
Of course, we can silence notifications, put on noise-cancelling headphones and work with applications that take up the full screen (tab clutter causes a significant drop in productivity, according to one 2021 study). Even when we've done all that, however, there's still the enemy within to contend with.

COULD MARINE CLOUD BRIGHTENING HELP US FIGHT CLIMATE CHANGE?
The theory behind marine cloud brightening is that brighter or whiter clouds reflect more sunlight back into space.
IS IT SAFE TO RUN EVERY DAY, OR SHOULD I DITCH MY RUN STREAK TO SAVE MY KNEES?
A running streak, where you run every day without taking rest days, can be highly motivating and beneficial for overall fitness. Running is great cardiovascular exercise and isn't to be discouraged (and finding a routine with some consistency is great). Getting a bit of exercise as often as possible is also hugely beneficial for your mental health.
WHAT MAKES THE MEDITERRANEAN DIET SO GOOD FOR US?
The Mediterranean diet may help you live longer, especially if you also adopt the lifestyle of people living near the Med during the 1950s.
WHAT IS MEXICO'S BLUE HOLE?
The world's deepest blue hole (marine sinkhole) lies off the coast of Mexico's Yucatán Peninsula. It's at least 420m (1,378ft) deep, but explorers still haven't found its bottom.
HOW CAN I TELL IF I'VE GOT HIGH CORTISOL LEVELS?
Cortisol is a hormone produced by glands in our bodies called the adrenal glands, which sit above the kidneys. It plays a critical role in various bodily functions, including regulating metabolism, reducing inflammation and helping the body respond to stress. While essential for our health, chronic elevation of cortisol levels can lead to several issues.
THE LUNGFISH
In 1836, European scientists discovered a peculiar animal from the River Amazon that they struggled to identify. Its eel-like body was a few feet long and its air-filled lungs persuaded anatomists it must be a reptile.
ARE WE THE ONLY SPECIES TO HAVE BEEN THROUGH A STONE AGE?
The Stone Age might conjure up images of early humans, sitting around a campfire or hunting prehistoric beasts, but evidence shows that we're not the only species that has learned how to work with stone tools. Wild chimpanzees (Pan troglodytes) use stone tools to crack open nuts.
Should we scrap daylight saving time?
Most of us look forward to the extra hour we get in bed every October, but researchers argue that changing the clocks twice a year harms our health
THE INTERNET OF ANIMALS
SCIENTISTS ARE USING ELECTRONIC TAGS AND SATELLITES TO TRACK WILD ANIMALS AND CREATE A DATA NETWORK THAT COULD HELP US ADDRESS THE BIODIVERSITY CRISIS
MUSIC FOR A DISTRACTED GENERATION
The number of things competing for our attention is often overwhelming. Can dreamy soundscapes created with neuroscience help our bewildered brains to concentrate?
