I am a child of the 1980s.  Some of you may have been born either before or after that decade yet one thing we all have in common is being handed a bit of money (for example 16p for a Mars bar in 1980, more on that later) to nip out to the shop for a bar of chocolate — a Mars bar or a Yorkie, ideally — and rushing home with the comforting weight of that piece of confectionery in either our hand (careful, they melt) or pocket (wrappers on, please, in order to avoid lint).

However, in the mid-to-late 1990’s and noughties the confectionery makers started surreptitiously reducing the size of their products: Yorkies lost a piece, from six to five, and shrunk by 20%, Wagon Wheels were hit with a 12% loss of mass, from 79mm to 74mm, and you are now lucky if you get more than a handful of crisps in a packet.
