We can take some care of ourselves. One cannot live a life with a death toll. All that matters is that is going to kill us and we must quickly find a way to avoid it. Aging is the single greatest cause of pain and suffering in civilized countries. It's also pathetic why most scientists prefer to study diseases that affect only a few rather than aging which affects everybody.
Many people claim an end of aging is impossible while others claim it's possible but undesirable.
Its's to be more afraid of life than of death. My future is a future of unknown paths and perspectives. My future might be to die tomorrow in a car accident or it can involve a holiday in Mars by the year 3000. The future belongs to those who believe in the beauty of their dreams. Even that we can control aging we will eventually die.
