The irony of white people trying to make their skin darker while simultaneously deriding those with dark skin is not lost on me. I mean, how crazy is that? I will never understand the psycho-anthropological underpinnings of class stratification. A person is a person is a person, regardless of appearance, although I know many people who have a different opinion than mine. They're wrong.
Has anyone other than me ever wondered why fur seems to prevent animals from getting sunburned? Why do these wavelengths of light not penetrate an elephant hide? Or a dolphin's epidermis? Surely the manufacturers of sunscreen have looked into what prevents marine life from the sun's detrimental impacts. I understand that the deeper one dives in the water, the less the rays are able to penetrate. Do we know why? Is diffraction that strong? If it is, why do I need sunscreen when I'm in water?
Sigh. OK, I'll stop thinking now.
