Now we're finding out the popular brands all contain harmful chemicals that soak through skin to disrupt your endocrine system by emulating hormones and promote thyroid problems, cancer and heart disease. See link below. So I've been looking up the Amazon user reviews for some of these "safer" formulas, and most of them seem to be pretty unpleasant to use (e.g. greasy white film, don't spread well, etc.)

Also I'm finding out from other sources that thyroid problems and Vitamin D deficiency seem to go hand in hand. Maybe we should just skip the sunblock and cover up like Bedouins, or risk skin cancer (at least you can see it) and make Vitamin D. Seems we're screwed no matter what.
