The latest bulletin from Carphone Warehouse’s Mobile Life research into the impact of mobile phones on our daily lives includes the usual mix of the unexpected and the obvious.

• One in three people would not give up their mobile phone for a million pounds or more (yeah right)

• 76% of people believe it is now a social requirement to have a mobile phone

• 85% of people think having a mobile phone is vital to maintaining their quality of life (but one in five 16-24 year olds think having a mobile phone decreases their quality of life)

• Most young adults feel mobiles are not just a tool, but a critical social lifeline for feeling part of a friendship group

• Most 16-24 year olds would rather give up alcohol, chocolate, sex, tea or coffee than live without their mobile phone for a month. But the majority of the those aged over 45 would rather give up sex, chocolate, alcohol and their mobile phone than their favourite hot drink
