People Grow Old
People are born as tiny creatures who know nothing about this world and people in this world. Though, with the time they grow elder and they find out a number of interesting things and facts about this world and they grow interested at this world and they are thirsty for this life and everything in this life. When they are kids they have a lot of desires but few opportunities.
When people grow elder they have more desires and more opportunities to make their dreams come true, though, they also have a number of duties they have to care about and so sometimes they have no chance to use those opportunities. They believe they will have more time for this later and they are waiting for a day when they will have more time.
Though, when they have more time and less duties there is nothing they can do anymore. People lose everything they use to have and they have the free time they wanted but they have no opportunity and they have no desires actually. They are old people and they a bored with the time free of their work and their children and other things they don't have.
People grow old and they have nothing in their lives except the free time they were waiting for. Though, it appears that a free time is the main problem of this life and they have nothing and no one to spend that free tome for.
