Ear infection --> coma.
She'd had a doctor's appointment for her ear infection, but rescheduled it for next week when a job interview opportunity came up. Two days later, her brain was riddled with tiny infarctions.
To everyone's relief, she seems to be coming back out of it, but if she does recover, it'll be a long, hard process.
So I'm thinking about all the workaholics I know who would have made the very same choice she did--to blow off taking care of her health for a week for work's sake. Y'all know who you are. Take care of yourselves, dear ones.
