Monday the US Surgeon General said 20 million Americans have asthma, but most aren't controlling it, a mistake that could be deadly. Far too many people depend on inhalers instead of medication to prevent an attack.

For World Asthma Day, experts are encouraging patients to take the asthma control test which you can find on-line. It contains five simple questions that let you know if you are over-using inhalers and if you should talk to your doctor to get your asthma under control.
The American Lung Association estimates that every day 5,000 end up in the emergency room and 12 people die due to uncontrolled asthma. So, for that test, click here.
