Well yes but a lot of things were considered fine a long time ago that we now know to be dangerous. Things like smoking, drinking while pregnant, not using seat belts. Hell my parents used to turn the back seat of the car into a bed and put us to bed in pjs, duvets etc no seatbelts and drive down the bloody motorway! Wouldn't do that now. It was a perfectly normal thing to do then, it isn't now.
