How long will you live? Maybe 100 years. If you die without recognizing the Creator, and especially the salvation work He did through His Son, Jesus, you are on a highway to Hell... not the reasons in the body of the OP comment. All the stuff in the OP comment does is to promote fear, when no fear is necessary.
Get into reading the Bible, particularly the New Testament, and realize that death holds no fear for anyone.
I think OP is just referring to the current happenings in different countries. Every news outlet out there always reports things that will make everyone anxious. With the current situation that we have, you cannot blame OP for worrying about his/her future.
It is good to have a belief related to the afterlife, it will let you hold on and persevere in trying times. However, let us not dismiss that the present life is real and we are living in it right now. We cannot just neglect the life here on earth because there is a life to come. Even Jesus provided food to the hungry and fed the five thousand with loaves and fishes and wept when Lazarus died (even though He resurrected him after).
I don't want to sound too religious but @BADecker is right, everything happening in the world right now shows that man has a need for something they have lost, everyone needs christ more desperately than we need any other thign right now, clearly we are in the end time as the bible stated, look out the world right now, they is no country that isn't going through a phase, news of war here and there, the truth is technology is not the solution to the world's problem anymore and may has to go back to the ways of old, the teaching of great men like Abraham in the bible, everything point that for man to have peace we need GOD and we can only see him through Jesus christ.
