The massive connectivity which has brought 24 hour entertainment is preventing couples having as much sex as they did in the past, according to a Cambridge University statistician.

David Spiegelhalter, the Winton Professor of the Public Understanding of Risk, said their had been a notable decline in sex rates over the last 30 years.

In 1990 couples had sex around five times a month, but now it is just three times, a 40 per cent decrease in just 20 years. Although unlikely, if currents trends continue as they are couples will not be having sex at all by 2030.

Previously researchers have warned that couples are killing the mood by bringing their iPads to bed. But Prof Speigelhalter said it was probably the rise of ‘massive connectivity’ embodied by Netflix, smartphones and box-sets which meant people never needed be bored.
