Vitamin D is completely underrated in damn near everything? Why? We humans share 60% of the same genes as a head of cabbage, we are 60% water, we need sun. Lookup MS and Lymphoma and then look up all of cancer, the nearer you are to the equator the less cancer there is, aside from skin cancer. We humans need the sun/Vitamin D and water to survive. https://pubmed.ncbi.nlm.nih.gov/35432612/ Bottom line, logoff, get outside and take a walk in the sunshine. (I would get out more if everything wasn't frozen and two feet of snow as the elements were not trying to kill me off.)
