A Power of Attorney (POA) is a legal document that authorizes another person or persons to handle your financial, legal, and in some cases your health matters. This can be a very helpful document if you are unavailable - for example if you are traveling abroad and have a loan closing to attend. A POA can be critically important if you become disabled and need someone to act on your behalf - for example manage your finances, pay taxes or authorize medical treatments.
Write something about yourself. No need to be fancy, just an overview.
