Life is Like a Wheel

My Uncle was a soldier. Because of the distance from his family from time to time that they had to be in a mission, he had to give up. Now he is into Armed Services job search. He is considering going back to the service but the question is if he will be accepted again. He is somehow devastated being jobless. He applied in a security agency before but the night shifts made him resigned also. Now, he is not fit for those jobs. He gained much weight and the soldier stature that he once had is completely lost.
