Hi, I'm Mr. Age. Dark winter mornings drag your mood down. A ten-thousand-lux light box, twenty to thirty minutes within an hour of waking, is the best-supported fix when there's no real sun to step into. It anchors your body clock and lifts the seasonal dip. Stop if it gives you a headache — but for most people, it works. Generate your prime age! More protocols like this on agegen.ai.
