Beta, even with 1% having the disease, a positive test doesn't mean you're doomed—most positives are actually false alarms. That Bayes logic calmed my heart when they screened us retirees for that rare vitamin deficiency last year. The doctors got all serious over my result, but my old friend, a retired maths teacher, sat me down with chai and explained the numbers…wah, it turned out I was perfectly fine. These tests, they scare you more than the Delhi heat!
