He’s Jonathon Sullivan, whom I met when he was a student at the Viable Paradise workshop on Martha’s Vineyard. I’m one of the teachers. He’s a promising fiction writer, and meanwhile he’s an ER surgeon and a martial-arts guy. This is his account of what he did Saturday: a lively day, but nothing unprecedented (unless you count the case of neurosarcoidosis). If you like it, there’s lots more; just nose around and you’ll find it.
