Traditionally, elders in certain tribes chose when they wanted to cross over. They would leave the village and die alone. They understood that death was a cycle and a part of living. There was not the fears associated with death , as it is today. People, also understood if the had become a burden to the welfare of others. Today, people are medically kept alive after the body has given up. The costs are staggering. So the question , is who are we keeping people alive for ? Is it their wishes, or loved ones who selfishly  want the final months or years, in spite of the lack of quality of life? People should have the right to make their own choice.
