Life is too short... I think every single human being on this earth had this thought or will have it someday in the future. Why this thought bothers us so often? Is it the fear of death that keeps us unrested or is it something else?
When you are young time moves slow and you think that you are going to live forever. Your knowledge about the world is narrow and inflexible. It seems to you that you know everything but life is straight and easy, even boring sometimes. You cannot foresee what will happen to you next couple of days based on today’s events. In fact, you don’t need it; your ability to analyze your past is also no too great, your day is too long and is a life in itself. But as you grow up, your abilities to process data are stronger, the information flow increases and your capability to perceive is enough to bring a whole lot of fun in your life.
