Dust: won't cause asthma, has no calories

According to the Woolcock Institute of Medical Research, Sydney, you no longer need to obsessively vacume your house to avoid asthma. Their research, which followed 600 kids with high risk family histories, suggests that "avoiding house dust mite allergens from birth does not prevent the onset of asthma, eczema or atopy in high-risk children." Marjorie will be pleased.
