Loss on a slow schedule is nearly invisible. Health, opportunities, and relationships tend to go gradually enough that no single week registers as a change, which is why people are surprised by the total when they eventually look. Nothing about this is dramatic, and that is exactly what makes it so easy to miss. The rate is steady and the awareness is not.

Check in on the slow things at intervals rather than waiting for a signal, since none will arrive. A yearly look at health, at the relationships you value, at where your time goes. Gradual losses are the ones most responsive to early attention.
