J. had some incredible luck, given that he did have the attack. He's in our N.J. office, and was alone in his office at the time but was on the phone to another co-worker of mine in our Idaho office. When J. quit responding to M. and she heard loud wheezing, she hung up, called the main N.J. office number, and told them to go check on J. Through more good luck the office was in the middle of CPR training that afternoon. Someone grabbed the experienced EMT who was teaching the class and the office's newly purchased defibrillator, and were able to revive J.
On a normal day, the main phone wouldn't have been manned at 4:30 when J.'s attack happened, so M. might have needed a lot longer to be find anyone to check on him. And if J. hadn't been on the phone, of course, he'd probably have died before anyone found him.
