During a physical examination this morning the neurosurgeon asked if I had lost any “crispness of perception?” Admiring the phrase seemed to spur him to increasing heights of eloquence. I learned how the spinal cord and spinal nerves are protected by a column of “cavity blocks” (vertebrae), they “live within a house of bone”. We looked at my scans, cerebrospinal fluid and the nucleus pulposus were mentioned, medical terms can be worrying or reassuring depending on the countenance of the speaker. The surgeon seemed optimistic. Finally, standing up from his chair, he exhorted me to “go and live your life”, and assumed the position of Superman about to take flight.
