And talking of the NHS, if you want save lives then have ambulances arrive on time. Unblock the roads that prevent ambulances getting there on time. Stop migrants flooding the country so taxpayers can get NHS treatment in good time. Provide proper dentistry to poor people. Provide timely health services to people who have paid taxes all their lives. And THEN you can talk about the TINY fraction of people who suffer from the ever improving air quality (unless they travel on the tube).
