Dainty little plants get all their energy from the sun. Have you ever seen a plant? Plants are pathetic. You just brush off them the wrong way they'll fall apart. You could hold up a leaf right now and probably blow at it hard enough for it to tear. But the plant sits out there in the sun all day and it not only survives, it thrives on the bountiful energy provided by the sun. And I'm supposed to believe that my rugged sophisticated human skin, which is so resilient and other similar words, I can't have my skin exposed on a hot day without my skin being like "oof ouch the sun oh no the sun"? Bullshit, they want to keep you from gaining the sun's energy, they want to keep you from having sufficient vitamin D.
