What do you think caused your ALS?

In the intrest of finding a cure for ALS, I would like to pose a question to people that have been diagnosed with ALS. Based on your history, lifestyle, exposures, family background, what do you think caused you to be "catch" the disease? Keep in mind, that you don't have to right about your answer; the objective of this question is to get your gut feeling about what caused the disease in you so that maybe we can gain more insight into what causes the disease for everyone.
