It’s hard to say. In many parts of the world, death is defined as the absence of brain activity. Other places still insist that patients be considered alive as long as medical technology enables them to maintain a pulse. In these cases, the line between life and death is irresolutely blurry, and we are forced to make hard decisions in the absence of more definitive circumstances. Life is a precious gift, but it can also be a terrible burden to both the patients and their families. Knowing when a person’s life has come to an end, though they may technically still be considered alive, is critical to determining when it is time to take someone off life support. It’s not an easy decision, but it is one you might just find yourself faced with one day. Talk with your loved ones about whether or not you would want them to keep you on life support should something happen to you. It’s always better to be prepared.
