My body appreciates how I care for it.

Appreciation from a body does not arrive as thanks. It arrives as reliability.

It woke you at roughly the right time. It digested a dinner you do not remember eating. It carried you through a meeting while your attention was entirely elsewhere. No note, no acknowledgement — just the absence of trouble.

That is the return on whatever care you have managed: sleep, water, the walk you took on Sunday. Small deposits, quietly repaid. It is easy to miss, because a good return here looks exactly like nothing happening. Every uneventful day is the receipt.
