World’s latest medical phenomenon is Separation Anxiety Disease (SAD) which occurs when people are separated from their mobile phone.

According to research by juice company Innocent carried out amongst 2,000 adults some 30% of us check our phones every 30 minutes, presumably when awake, and 25% suffer boredom when parted from their phone for more than one hour, with 23% saying this separation made them feel anxious.

There is little sympathy, sadly, for the millions of SAD sufferers with 35% of the responders say that their biggest bugbear was people using their mobiles at the meal table (restaurants to note this one) with another 28% annoyed by people checking their phone in the middle of a conversation, and 23% by them being used in the cinema.
