Social media likes are also a key concern, with youth in the UK admitting they spend five minutes on average editing photos before posting them and expect to get a minimum of 44 likes.

Discussing the research, Patrick Fagan, consumer behavioural psychologist from Goldsmiths University, said: "Although we're earning more as a country, life satisfaction has barely moved since people started recording it.
"We are instinctively hardwired to look for problems. While we used to fret over rent and job security, our concerns have now transmuted into more fickle problems. In our comfortable lives, we might have enough money for bills or a holiday, but it's in our nature to never be satisfied and we will worry about wi-fi and delivery times instead."
The survey results found that two thirds of the nation describe their work and social lives as either extremely, very or fairly busy and over half of Brits feel this is due to there being more to worry about today than twenty years ago.
Patrick suggests this is another reason why our concerns have amplified in recent times.
This view is also reflected by three in five over-50s, who think people in their twenties have a busier life than when they were of that age, due to working harder and spending lots of time on social media.
