<s>[INST] I had a customer that starting white as a ghost and started passing out and next thing he was urinating on himself. It was very dramatic because the paramedics couldn t save him. He was only 27 yrs old, 6 5 and like 300 lbs. What do u think happened to him? He was pefectly normal when he walked in ..... Please help I would like to know because I keep wondering if we had only called 911 sooner would he still be alive? [/INST] It sounds like he might have had a blood clot to the lung/heart or a serious heart arrhythmia that caused his heart to stop beating. He also might have had a sudden brain hemorrhage from an aneurysm or something similar. Such events are quite Chat Doctor.  It would not have made a difference if the paramedics had been called any sooner. You did the best you could and this is just a very sad situation. Hope this helps. </s>
