Teenagers used to rebel by smoking, doing drugs and getting pregnant. But in Britain, modern 14-year-olds are eschewing these traditional forms of acting out - in favour of hacking computers from their bedrooms.
Figures from a study carried out by University College London suggest that more teens of this age have hacked a computer than have had sex or are regular smokers.
One in 20 teenagers in the Millennium Cohort Study, which follows children as they grow up and asks them questions about their lives, told researchers they had hacked a computer in the past year. Just under 1 per cent had sent a virus.
Two per cent of 14-year-olds of either gender said they had had sexual intercourse, with almost 11 per cent telling researchers they had had some kind of intimate sexual contact.
Three per cent said they were regular smokers.
