Sarah Keyworth - Are You A Boy Or A Girl?

Sarah discusses why our brain's initial response to a new person is to instinctively work out what they gender they are. Is this because we are taught to do it as children? To help Sarah analyse why they think this is the case, they look back on their own childhood which includes a vivid memory of being on a beach in France with a man selling donuts - the baked goods, not the inflatable rings.
