91 Alchemist

Some people sleep lightly, while others sleep deeply.

In my previous life, I often woke at the slightest sound, so I had always thought of myself as a light sleeper.

But when I considered how I had nearly been late for the academy because I failed to hear my alarm, I began to wonder if I was actually the type who couldn’t wake up easily unless someone forced me to.

I suddenly remembered something my master had once told me: the human brain remembers experiences of deprivation.

For example, intermittent fasting that involves eating only one meal a day might be an effective short-term dieting method, but the body adapts to the reduced food intake, gradually increasing its calorie absorption rate.

I heard that this was also one reason people became more vulnerable to the yo-yo effect, along with their desire to compensate.

Had not getting enough sleep as a baby been the cause?

Even then, though, I had never particularly felt as if I lacked sleep.

If anything, I might have suffered from insomnia because I was afraid I wouldn’t open my eyes the next day.

Of course, this body had its advantages, too...
