[ WP ] Story about a superhero whose powers come with a strange side effect or drawback

The ultimate power. The ability to stop time. Affect the world around me. I used my powers well when I knew I first had them. Stop time, work out, read, and fix a problem in the world. Stop a rape, or a murder. Fall back into my regular life. Seemed like a dream. Until I found out what exactly happened to me while I stopped time. I aged along with it. It was n't noticeable to me for the first few years, as I never stopped time for too long. Scared something would happen. But when I turned 40, my doctor pulled me aside. He was amazed, that even though I was in great shape, and ate right all the time, I had the body of a sixty year old man. I went home that night and thought to myself long and hard. 
 
 I remembered how I first gained my powers. An incredibly old man had come to me and told me he had been watching me. Made sure I was worthy. I gained my powers from him. My life was short. Too short. But I will pass this burden on to some other young one. After one last thing. I had always wanted to visit the playboy mansion.
