The reason for interest in Gehrig’s records is that stuff from last year in which it was speculated that, rather than ALS, he may have died from some sort of disorder that, while manifesting itself like ALS, was really the result of multiple concussions he suffered during his athletic career.
I know a lot of people will probably freak about this because we’ve gone insane about privacy in this country. Yes, I acknowledge that identify theft and insurance discrimination and all of that is a problem and I agree that safeguards have to be in place to protect folks, but the rhetoric surrounding “privacy” has gone beyond reason and is in fetish territory. Spend some time with a lawyer who does a lot of Freedom of Information Act requests and find out how much privacy you really have. Less than you think, I bet, and it’s generally OK.
Personally I would hope that a bill like the one proposed here is driven less by mere historical curiosity and more by actual medical utility (i.e. researchers can find value in looking over old medical records). But really, if you’re dead 50 years, you’re dead 50 years and I don’t see any grounds for objection beyond appeals to amorphous privacy concerns.
