But it happens! Life isn't always cut & dry.
Two years ago, I collapsed in the sun. When I came to, the paramedics had already pumped a bag of fluids into me & I was halfway through the second bag. On the way to the hospital, they administered a shot of adrenaline. I also vaguely remember two additional shots, but I was in & out of consciousness, so I don't know what they were.
I spent 12 hours in an emergency treatment room. Test after test, doctor after doctor & bag after bag of fluids. My kidneys were close to failing. I finally leveled off & spent the next 17 hours in observation.
I didn't know my body was in crisis. I felt fine up until a few moments before I passed out. You'll probably judge me as not being too bright, but there's a story of how I got to that point. If a sensor on my watch would have alerted me that I was in trouble, things might have turned out differently.
