I grew up in the Seventies. In some ways, it’s a miracle any of my generation are still here. Puffing on fags was widespread and no-one had any namby-pamby ideas about protecting children from second-hand smoke. Seat belts were a rather louche extra feature and our playgrounds featured high, steep slides, witch’s hat roundabouts that offered an exciting opportunity to injure yourself and of course hard concrete on which to fall.
