This article describes an 81-year-old woman who got a tattoo reading "Don't euthanize me" to express her medical wishes if she were incapacitated.
The Calgary grandmother recently had the words “Don’t euthanize me” tattooed on her arm.
“It’s drastic, but this very clearly says, ‘I’m going to live until God’s ready for me’,”
Would medical instructions tattooed in this way be legally binding in the absence of more recent legal documentation (e.g. an advance healthcare directive)?
For the purposes of this question, let's assume that the tattoo gave an explicit medical directive that would not be the default medical procedure (e.g. "do not resuscitate", "don't intubate me").
