So I know the jist of his origin but was just reading the new run and began to wonder, what makes Matt special? Like why are senses heightened, just because he's blind? Shouldn't there be a bunch of other Daredevil's then if the only prerequisite is being blind? Was it to do with radioactive stuff? Or never really explained? I'm sure this is common to knowledge to most people but really curious now and couldn't find the answer anywhere, thanks.
