You are most likely to die from either old age or cancer, though you had grown old by then, and had lived a long, healthy, prosperous, and happy life, and you had accomplished your goals and the legal of you, shall live on and to prosper for the years to come. Your time had then passed, and as you are surrounded by your family and friends, both young and old, you shall pass on to Heaven, and be able to see your family on the other side.
