I definitely think the Brady panic attack was staged.
However, I grew up in a very rural area, where there were only 2 ambulances for the whole county. When my Dad started having chest pains, we drove him to the ER because both ambulances were en route to the same ER. It sucked, but it was faster than waiting up to an hour for a paramedic. Fortunately, our neighbor is a nurse and rode with us.
