Indeed, and that is what our computerised system for prioritising calls does as well. I treat *everything* as a serious call until I've whittled away the nasty things with a mixture of history taking, observation and consideration of vital signs. So, while I might say to my crewmate on the way to a job, "I bet it's a load of old rubbish", we'll still get there as quickly as is safely possible and we'll still not jump to any conclusions. Jumping to conclusions is an easy way to find yourself standing up in front of the coroner's court.
