She’s a type-one diabetic, she’s never had a lot of money, and for years she didn’t have health insurance.It hasn’t been easy, but she’s become a master. “There's only three things that you're fighting,” she says. “Problems with competence, problems with greed and problems with maliciousness. And luckily most things are incompetence.”She has saved herself and her family many thousands of dollars, and made a habit — even a hobby — out of helping others: Fellow diabetics, co-workers, and strangers on the Internet.She's a health-care ninja. And she happens to be my neighbor.Also in this episode: Our show's chief investor (and my spouse) applies some ninja-level negotiating skills to save our family more than $700 on a lost medical device. Around here, that's what we call romantic.Thanks to our supporters on Patreon!
