The melatonin headline made the rounds this week. Ninety percent higher risk of heart failure. I got messages about it. Smart people. A few of you. Here is what it actually is. A conference abstract, not peer reviewed. Observational, so it cannot prove cause. Users pulled from prescription records, which means every American buying it off a shelf got counted in the control group. And the people who take melatonin for a year straight are the people who cannot sleep, and insomnia on its own is hard on a heart. So: weak signal. Watch it. Do not reorganize your life around it. I am not posting this because I care about melatonin. I do not. I am posting it because the reflex most of us have when a headline lands is to look for someone to tell us the answer. And that reflex is the whole problem. Twenty years in emergency medicine taught me one thing that transferred to everything else. You never get certainty. You get a probability and a clock. The information will always be partial. The pressure to decide arrives anyway. That is true of a supplement. It is also true of the pivot you are sitting on, the offer you have not sent, and the conversation you keep not having. Waiting for more data is a decision. Usually the worse one. So, the ask. Name one thing you are currently stalling on because you are waiting to feel more certain. Just the thing. One line. Do not explain it.
