Someone I used to know in California died rather suddenly. It was about 20 years ago. She and her husband were casual friends of mine. The perfect yuppie couple, they had everything going for them. Then she started having back pain. They were into fitness and perhaps the back pain was due to some sprained muscle while at the gym. A few visits to the doctors, a few more to chiropractors, a bit of muscle relaxants and pain killers, a few more visits to the medical establishments—a few months went by and the symptoms kept getting worse. Finally, it was diagnosed as cancer. She died within six months of that determination. It was later said that if they had discovered what the problem was, she might have had a fighting chance against the cancer. As it happened, she had lost too much time while her misdiagnosed symptoms were being treated.
