<human>: Give me a shortened version of the text

Last night i was arguing With my friend and we got onto the subject of pcp and the human body. He stated that "a person on pcp could survive being shot longer than a normal person" so I told him that pcp is not some sort of magic invincibility powder and that a person that got shot well on it ,In fact, would probably die faster then a normal person. My reasoning was that wouldnt feel the pain and bleed out, where as a normal person would pass out and retain blood flow for a bit longer. After telling him this however he stated that "because the brain doesnt make the connection, the person will stay alive for longer". So i explained to him we need blood flow and oxygen and that your muscles  and internal organs would be pretty much useless without it. However he kept repeating "but the brain doesn't make the connection so they'd still be alive" and eventually he just flat-out said "yeah but you don't need blood flow" and "some people don't need oxygen, it's a defect in their brain but pcp has the same effect". I was pretty shocked at this point so I tried to tell him that the heart and lungs are in fact, not completely worthless organs, but unfortunatly the argument ended with "SHUT UP! JUST SHUT UP! YOU OBVIOUSLY HAVE NO IDEA WHAT YOUR TALKING ABOUT, IM IN A HEALTH CLASS SO I WOULD KNOW MORE! 
(BTW im not making any of those quotes up, I figured I would say that after I realized how crazy they sound)
<bot>: tried to explain to a friend that we need oxygen and blood flow, he exploded, I lost a bit of respect for him.
