I would've, but total painkiller means you no longer have a sense of touch and thus can't handle anything without extreme difficulty.
True, but not necessarily so.
Theres a condition where you can still feel pain but you arent bothered by it at all, painkiller might do something similar.
Of course if thats not the case and it does kill all your pain receptors, you wont know when you need to pee and that could be embarrasing.
You've got some weird anatomy going on if you're using pain to know when you need to pee, man. I would think mechanoreceptors (Lamellar corpuscles, I think, are the ones involved in sensing pressure - which, I think, is probably the first sensation involved) would trigger before nociceptors.
Say, Pyro, did you ask for that information, or did pw propose it? And if first, why did you want it? Not like you gonna be able to use it for a long time. Or just to rub it in our noses 
PW proposed paying me in information - thing is, with current rank and station, I have access to pretty much anything I want to know and probably more (It might sound a bit facetious, but I think that, if Simus wished, she could probably get Steve to tell her the same things he's telling Miyamoto. She may not be a General, but she is in control of what is pretty much the revolution's only source of supplies). It was actually suggested in the DJ chat that I ask about Nyartefact labels - and why not? It's harmless information for me to have, now, and it will be amusing seeing you guys try to work it out.
