It's very sad news and I still ask myself what to make of it. Seth influenced my own QS journey a lot. In the end the it seems like extrapolating health from the kind of data he gathered wasn't possible.
His approach would be expected to optimize for common situations, which may not be the same as optimizing for rare situations. I've been working on a theory that health is not a single thing.
For all I know, he had some intrinsic cardio-vascular problems, and his self-experimentation led to him living longer than he otherwise would have.
You know the drill - If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
And, while this is an accidental exception, future open threads should start on Mondays until further notice.
