Do I have to be ill or disabled in order for someone else to act under my power of attorney?

If the power of attorney is a “durable” power of attorney, you do not have to be ill or disabled for someone else to act as your attorney-in-fact. Your attorney-in-fact can act on your behalf for any reason. For example, if you are traveling abroad and you need a document signed, your attorney-in-fact under your durable power of attorney can sign the document on your behalf.
