The deadly truth about a world built for men – from stab vests to car crashes

This excerpt from a Caroline Criado Perez's new book exposes lots of data biases and miscalculations that treat the 'average man' as the default user, even though men on average are heavier, taller, run hotter, have deeper voices and a different typical heart attack symptoms. This puts the average woman, at a disadvantage almost everywhere she goes in life – sometimes dangerously (seatbelt design), sometimes merely annoyingly (aircon temperatures in offices). It really demonstrates to me that if we're going to get an equitable world we have to rethink almost everything. That's what radical means: from the roots (radix = root. Think radish).
