If you watch any pre covid media sudden deaths and young heart attacks or collapsing for no reason are so rare they're used as plot devices to build the over arching mystery story. It's so rare that in real life when the only people dying suddenly in their sleep were south East Asian men the FBI thought they had a racist serial killer, turns out it's a rare genetic disorder only in Asian men. Don't let them tell you this is normal. Tell everyone you know this is not normal.
