When I developed asthma in my mid-30's, I was prescribed a ventolin inhaler (the blue one). I suddenly found at work that quite a few of my mates had one about them - something I hadn't previously noticed. I bet that everyone either suffers from asthma or knows someone who does - my wife, a teacher, has a whole drawer full of inhalers for the kids in her class. I'm convinced that we are wrecking our kids' health (and our own) through the proliferation of modern chemicals, processed food etc. etc...
