Most printed books come in certain standard sizes which have been used for hundreds of years. Even the dimensions of Kindles and other eReaders are derived from these norms of printing. And where did these standards come from? According to medieval scholar Carl Pyrdum, they're based on the size of a sheep:
The whole sheepskin, flattened out and folded in half, is one common size. Fold it again, and it's another size. All of these sizes and dimensions are still being used by printing houses in the 21st century. The Kindle, for example, is the size of a sheepskin folded over three times. Pyrdum provides further examples and concludes:

The question then becomes, I guess, why were medieval books the size they were? And the answer to that is simple: medieval books were the size they were because medieval sheep were the size they were. Remember, paper wasn't the original medium for page-creation. Medieval books were constructed of parchment, which is a fancy word for sheep or goat skin (and primarily sheep skin, because there were a lot more of them around).
The whole sheepskin, flattened out and folded in half, is one common size. Fold it again, and it's another size. All of these sizes and dimensions are still being used by printing houses in the 21st century. The Kindle, for example, is the size of a sheepskin folded over three times. Pyrdum provides further examples and concludes:
Next time you're squinting at your mass-market copy of Dan Brown's latest wishing the pages were just a smidge roomier, blame the medievals for not having bigger sheep.

I would prefer just to end this daylight saving folly all over the planet...
He does bring up many good arguments of stopping the practice.
Another version of the same myth claims that road accidents in Scotland are reduced by DST since it is lighter in the mornings in winter. Again this fails to work for two reasons; firstly in that the days are so short in the north of the country that the morning and evening rush hours happen in the dark in winter anyway; and secondly again the clocks are changed for summer not for winter.
Quite why these myths exist I don't know, but they do.
My personal gripe is that DST messes with my surfing. Often depending on the swell and the state of the tide the best surf of the day might come before work. There are times of the year in spring and autumn when there isn't enough daylight in the morning to get in a session before work when there would be if we stayed on winter time all summer. What I want is a window before and after work so I can get more chance to benefit from the optimum swell/tide conditions to give the best surf.
