and he was a sun-worshipper, spent a couple of hours on the beach every sunny day of his life in Florida. You would think he had Vitamin D in huge quantities.

Apparently, the angle of the sun has a lot to do with vitamin D absorption by your skin.

Did he have any co-morbidities?

Except during the summer months, the skin makes little if any vitamin D from the sun at latitudes above 37 degrees north (in the United States, the shaded region in the map) or below 37 degrees south of the equator. People who live in these areas are at relatively greater risk for vitamin D deficiency.

For this to happen, the sun has to be high enough in the sky for the ultraviolet B radiation (UVB) rays that we use to make vitamin D to get through the atmosphere to us. The sun is only at the right angle (higher than 50 degrees) above the horizon between May and September from 10am to 3pm.

No co-morbidities. Thanks for the map. He lived way below the line. I think he just waited too long to go to a hospital.
