What would do if you were told you might have to give up your dream career, because of health conditions.

Reflecting back on my years as a pilot, airline pilots often carried "loss of license" insurance. I can't remember the premium amounts but it wasn't terribly expensive. All based on health issues that may compromise one's ability to function. Periodic physical exams were required, ranging from every 6 months to longer periods depending on cockpit role. So it was very possible that the next physical exam could be the end of ones dream job. A few pilot friends lost their dream jobs on that next physical exam. But the exams also brought to light serious health issues that within a short time became very serious and debilitating. So, losing the dream job was but a minor distraction to what came next.
