I live online as much as I live offline. Often, I move around in the world staring into a device as I walk, sharing bits of one realm with the other. The morning I went in for my first mammogram, I felt nervous. I would tweet this new thing, like I do with lots of new things, and make the unknown and new feel less so. Maybe by doing so, I thought while I was driving, other women like me who'd never done this would also feel like it was less weird, less scary, more normal and worth doing without hesitation. I'd crack some 140-character jokes. I'd make fun of myself and others. I would Instagram my mammogram.
