For years, I thought my father was strongest person I had ever met. He worked hard most of his life and he was physical healthy. However, he had a seriously illness at the age of forty. My mother is always fighting alongside him. She suffered a lot of pressure as for his caretaker. She also managed to doing a full-time job and raise three children. My mother never lost faith that my father would be standing next to him again and the pair would be gardened together in the spring. It was her strength what kept my father alive. Fortunately, after 8 year of treatment, my father finally recovered.
