I can testify with certainty that it does.
What if I really don’t care if it works or niot?
Right-o.
Everyone can be broken because there comes a point where you just want it to end.
As a teen I screwed up and stayed out all night. My dad applied the lightest bit of “torture” on me when morning came. I had yet to sleep and he didn’t want staying up all night to be a habit that ruined my chores or staying in bed till the afternoon. So he made me stay up. If I sat or laid down he tossed a shot of water in my face or grabbed me by the shoulder and made me stand on my feet. He made sure I stayed up and walking around till I begged him to just let me sleep.
All it was was sleep deprivation and I was promising him I’d never stay out or up later than midnight.
I will not claim I’ve ever been tortured.
I have, however, been made “profoundly uncomfortable” for a couple of days.
It taught me one inviolable rule - “Save the last round for yourself”.
