It's interesting how in some industries we trust more then in others. For example, the law & medical industry we trust more then aviation industry. However the aviation industry has shown to be more reliable. So, how do you tell if you are a nervous nelly? Well if you you are nervous about everything  that can go wrong in the airplane , but at the same time you don't tend to worry as much if you get admitted to the hospital. If you worry at every strange noise you hear in an airplane, but you don't worry as much of the restaurants you eat at?  If you are more worried about the pilots making a mistake & less worried about the driver next to you then you are a nervous nelly. The questions is now what do you do about it? Live Life, and don't worry about what could happened, instead worry about what is happening in you life at the present. Focus on making life more meaningful. I remember a few years back of a couple who was so worried about a plane crash that they died on their way to the airport in the tunnel at Boston. For every person worried about dying in a airplane crash I could quote a story about a person who died on their way to the airport.
