I like some of your posts, technical specifics aside I'm glad people are writing about blood pressure and vitamin d. I'm glad you mentioned the steroidogenesis aspect of sunlight though be forwarned that my understanding is that much of this comes from oxidation of sulfite to sulfate whereby sulfation leads to increased regeneration of nad+ which signals a capacity for energy utilization which in turn then signals for steroid hormone production. An over simplification of course.

Your comments are just spam...you even copy and paste them to new blogs..
This is not good STEEMIT practice/ etiquette
It is much better to actually say something helpful or useful, not just spamming, hoping to get a few pennies of upvotes.
