“Do you all eat grapes?” James Hindman asks, proffering a bowl of green grapes at the outset of his one-man show, What Doesn’t Kill You, directed by Suzanne Barabas, artistic director of the New Jersey Repertory Company, where this show began its theatrical life. And while Hindman perhaps doesn’t want anyone to leap to their feet and grab a grape, this kind of seemingly non-rhetorical question is part of the audience intimacy he develops throughout the piece (and indeed some audience members did call out at various prompts, though no one took a grape). Hindman’s friendly, casual style establishes rapport, and once everyone is comfortable, he becomes a tour guide on his personal journey into and out of a New Jersey hospital, after suffering the kind of heart attack that one nurse refers to as the “widow maker.”
