I'm sitting in the nice sunshine and thinking about how the fear of skin cancer had warped my sibling's mind so much that they spent hours a week researching different types of sunscreen and settled for importing some weird, quasi-legal hippie goop and using it EVERY time they went outdoors - even for thirty seconds to pick up the mail.
And I'm thinking about our family's genetic risk of skin cancer (zero), and the benefits of going outside (many, including a reduction in heart disease, which our family is prone to), and how it must be both emotionally fraught and physically exhausting to lather every bare inch of skin in weird smelling goop every time you leave the house, and how hard it is to make yourself do something when it's so difficult.
And I'm coming to the conclusion that, paradoxically, my sibling's orthorexic obsession with health is actively making them less healthy.
