Fact of the week
In the UK, an old building standard called the "21-metre rule" is still used to protect privacy between neighbouring properties. The 21m (or 70 ft.) was set by urban designers Unwin and Parker in 1902. They derived this distance by walking away from each other in a field until they could no longer see each other's nipples through their shirts.
