Ariana Page Russell’s “Skin Two” is a collection of photographs where she draws patterns in her skin. It looks really painful, but as she explains, it’s just because she has dermatographia, “a condition in which one’s immune system exhibits hypersensitivity, via skin, that releases excessive amounts of histamine, causing capillaries to dilate and welts to appear (lasting about thirty minutes) when the skin’s surface is lightly scratched.” Apparently, it’s painless. via Chloe Rote ∞

I wish I was right handed. Several recent studies have shown that moving your eyes left and right for thirty seconds improves memory in a rote memorization test (659 words). Unfortunately, this only works for people with right-handed dominance. The hypothesis is that it increases communication between the hemispheres, which is already high in people who do not exhibit right-handed dominance. via Hacker News ∞
