Should I sign a power of attorney?

What?

 

If you don't know, offhand, I'd say no.

 

it depends on what it says in it. If it say's you are in a coma and you have a certain pecent chance of living or whatever, you dad can legaly tell the doctors to tak you off life support::for example. just form a contract that you have read and agree to if you haven't already

 

and you might offend your dad if you don't...i don't know if thats a factor or not
