If that "everyone over 50" logic holds, then we should also put the whole population on metformin, aspirin, and vitamin D, because they all show some brain benefit. The problem is that blanket prescribing stops being medicine and becomes a mass experiment. BluntForce compared this to statins, but statins go to people with high cholesterol, not literally everyone. GLP-1s cause real muscle loss and gastrointestinal issues, especially in people who don't need them. So either we accept that targeting by risk is the sensible line, or we admit the "everyone" framing is just hype. I'm with targeting and real evidence.
