I love the feeling of strength and vitality in my body.

Strength announces itself in use, never at rest. You notice it on the day you carry every grocery bag from the car in one trip, up two flights, and set them down without your forearms shaking.

Vitality is quieter still. It's waking a few minutes before the alarm and not resenting it.

These are small readings and they're the honest ones. Nobody feels strong in the abstract. You feel it inside one specific thing that used to be harder than it turned out to be today.
