A ray of light with a bright spot.


What are hiccups and what's the medical term for the phenomenon? How far to the horizon and why does it always appear to be at eye-level? What are lectins and are they harmful? What is pulmonary fibrosis, why does it happen and can it be cured? Why do bright lights make spots on my vision, and why does the colour change when I close my eyes? As a 65 year old in good health and with 4 Covid-19 vaccines and one mild SARS-CoV-2 infection, do I need another Covid-19 booster?
