The Unavoidable Four Pains in Buddhism

Why am I here? Why was I born? Nobody asked me if I would want to be born in this world. I'm here, I'm living. I have to try to survive, but I know I shall die. Why do I have to live knowing I would die? The same feelings come to me when I had a flu or disease. I haven't allowed any virus to assault me. How did they do that in my body? These, life, aging, disease, and death, are called the unavoidable four pains in Buddhism. Every person cannot elude any of them.
