I am a lifelong non-smoker. However, in common with the majority of my generation, I was brought up by smoking parents. It was the norm at that time and the dangers did not begin to be understood until the 1960s. One of my sisters (ironically a doctor) smoked until she became pregnant. None of the three of us has any obvious damage from exposure to smoke in our early years and the youngest of us is 68. I am not arguing for a return to smoking, but for less fanaticism about exposure to smoke. I don't like the smell of cigarette smoke drifting out of the local pub's garden, but I don't expect it to do me permanent damage. Smoke in the workplace is a very different matter and it's good that this danger was noted following a court case in the early '90s.
