Consider actually reading the post before commenting next time. I didn't do an "180" switch. I wrote:

As far as my deep dives into the science of sleep have suggested, any deficits in sleep, either qualitative or quantitative, result in essentially minuscule quantities of irreversible kinda-neurodegeneration. "kinda" because it's not neuronal death, just the failure to maintain important connections and peak performance properly.
Without much drama (like the "kinda-neurodegeneration" wording), this can be easily summarized as: optimal amount of sleep = you're at peak performance, otherwise you're working at less than peak mental performance.
