Don’t drink, don’t smoke what do you do?

I was just on the exercise bike and just thinking about this. I don’t do any of the above but why is my health do bad? Whenever I have a hospital appointment I am surrounded by old people, I don’t mind this but I just think that it is so unfair. Why couldn’t I have gotten to their age before having my health problems. My parents come with me to most of my appointments and I guess people in the waiting room think that I am taking them to the appointment. I am not overweight and have never been. I don’t eat the wrong foods so why does it all happen to me. I have never thought that I had bad health. I guess I was just thinking positively but I wonder if people who know me have always thought that my health was bad. I had a heart attack for goodness sake. Perhaps I need to take up drinking and smoke a bit as not doing it hasn’t helped.
