Lorca was incredibly ballsy. He didn't seem bothered by prolonged stays in the agony booth and likely asked Michael to be injected with the numbing agent only so he could fake his own death to do what he did to the other guy. His men, after being in the booths for 200 hundred days and plus were right as rain and ready to fight in a matter of minutes. I bet if any of us spent more than a minute in one of these things, it would take us weeks to recover and then years to overcome the ensuing PTSD!!
I'm sure I would have been sent to the agonizer booth pretty regularly times during my school years If I had grown up in the Empire. Toughens you up when used regularly, or so I hear.
