Getting the vermin out of Boston’s public housing may have improved living conditions in more ways than one: With the move has come a sharp drop in asthma symptoms among residents.
Boston health officials say new city data indicate that asthma incidences have dropped nearly by half since 2005. That is when the housing authority teamed up with the Boston Public Health Commission to reduce the number of roaches and rodents, while reducing the use of pesticides, which, along with roach and rodent droppings, can aggravate asthma symptoms.

Having reviewed the Bill of rights, I failed to see where people were endowed with a natual right of public housing for their lifetime. She is a "housing advocate" for her lifetime housing on the public dime.
Two issues here that have nothing to do with asthma: 1. this trained housing advocate has been a life long tenant. How do we train her kids not to repeat this. 2. when the average cost to own a dog (see photo) is $75-$100 per month, why does the housing authority allow tenants to have them. She would be, as would the taxpayers, better off if the money was put into savings for the kids college education, or saving to buy a home, or just get off the dole?
Maybe less thorough doctors or absence of the need to overdiagnose marginal cases?
