I never liked roller coasters. Maybe it is the feeling of being out of control, or feeling like I am going to die, or nausea I get from motion sickness. I choose not to get on a roller coaster voluntarily. Unfortunately, life is one big roller coaster and every day is full of ups and downs, twists and turns, and worst of all are the sudden drops. I do quite enjoy the smooth parts where I get to ride and look at the scenery, though.
