Interesting Facts

The average CD (compact disc) can hold 74 minutes’ worth of recorded sound. (What's interesting about this is why they chose 74 minutes.  Why not 60 or 120?  Well allegedly, when CDs were developed by Philips and Sony in the 70s, one of the developers,  Norio Ohga,  decided that a single CD should be able to contain the longest recorded version of Beethoven’s Ninth Symphony, which is 74 minutes long. Luckily they didn't decide on the symphony Victory at Sea, by Richard Rodgers, it is 13 hours long!)

In the 1970s 70% of mothers in the UK stayed at home full time. (In 2013 that figure is just 10%, but according to a survey by uSwitch, 75% of mums would like to be able to afford to stay at home and look after their children. Six out of ten mothers who return to work after having a baby do so only to pay the mortgage, or to ease financial pressures such as debt. Just one in seven said they wanted to develop their career.)
