To lose your mobile phone is unfortunate but to flush it down the toilet is especially careless, although common, if new figures are to be believed. Research suggests that 885,000 (drunk and sober) subjects of Queen Elizabeth helplessly watch their handsets disappearing into the ‘black hole’ every year. That’s roughly £342 million flushing (not contributing) to Her Majesty’s sewage network. The study also reveals that 810,000 mobiles were left in the pub each year, with 315,000 left in the back of a taxi and 225,000 on a bus. Pet dogs in UK apparently chewed their way through 58,500 handsets last year, while another 116,000 went through a spin cycle with the dirty laundry, reports The Telegraph.
