I suffered from asthma as a kid, bad enough to put me in hospital. As I got older, it just kind of disappeared - by the time I was 15 or so, I was only very rarely using inhalers. As an adult, I've travelled a lot to India for work, always staying in big cities, which are filled with 2-stroke rickshaws and are always heavily polluted (e.g. Mumbai, Pune, Delhi). Often a kind of horrible, acrid, thick smog descends after dark when the temperature drops a little. Every time I travel to such places, I have to take my inhalers because I really feel the effects of it! The first time this happened, years ago now, I was really quite shocked - how many deaths must this cause? How could the government allow this, and how could people stand it?
