seems to be mostly links about Warren wanting to make it harder to declare bankruptcy, and the gem of info that 62% of bankruptcies they studied had a medical cause.
A study published in the American Journal of Medicine in August 2009 conducted by professors from Harvard Medical School, Harvard Law School and Ohio University found that 62.1% of all bankruptcies in the study had a medical cause.
