In the past, when I got sick, I just felt uncomfortable and knew my body needed rest—my mind rarely dwelled on it. Back then, I was young, recovered quickly, and never realized that my body had anything to tell me. Illness was just a minor inconvenience in life, nothing worth reflecting on.

But this time was different. On a feverish morning, I stood in the sunlight and looked at my arm, suddenly feeling a sense of unfamiliarity. The texture of my skin, the loosening of its lines, and the way the light fell upon it all made me realize—my body is truly changing. In that moment, it wasn’t fear or sadness, but a quiet, gentle reminder: time has left its marks on me.

The sensation of aging is subtle. There are no dramatic ups and downs, just a faint awareness that gradually settles in. It made me clearly understand that I can no longer take my body for granted as I did in my youth. It exists at its own pace, silently recording the passage of time.
