Nietzsche on Pain & Memory

I recently came across this clip of Andrew Huberman discussing the effect of adrenaline on memory:

In general, we tend to remember negative moments over positive ones. This makes sense from an evolutionary standpoint, since our survival depends on not repeating hazardous actions.

Nietzsche made a similar observation in his Genealogy of Morals:

Man could never do without blood, torture, and sacrifices when he felt the need to create a memory for himself; the most dreadful sacrifices and pledges (sacrifices of the first-born among them), the most repulsive mutilations (castration, for example), the crudest rites of all the religious cults (and all religions are at the deepest level systems of cruelties) — all this has its origin in the instinct that realized that pain is the most powerful aid to mnemonics
