They pump insulin.

They're inconvenient, but much better than a few years ago. Having an app for the monitor now is a game-changer to avoid people hearing a self-destruct countdown beep under your shirt. But one of my friends actually still prefers shots three times a day, You just kind of get used to that if it's all you've ever known, so for some people it's not as big a deal as others make it out to be.

So with that out of the way, you may have replied to a comment mentioning insulin pumps, but what do they have to do with the post, anymore than the doll's hair colour?
