There's just such a great degree of certainty, i know, around what is fundamentally either just made up or wishful thinking. Even the things we think we know for sure, we don't even really fuck and know totally. It does appear that, like, blood types are correlated with certain disease outcomes. But it's not all that meaningful on an individual level to tie these kind of broad characteristics to your disease risk. And ultimately, what they're offering you as a security blanket that may or may not actually do anything for you.
