I just googled the MOST COMMON CAUSE OF DEATH it gives nationalities , ages, etc. NO WHERE IS ALS mentioned. Therefore people that twitch with BFS have NO MORE chances of getting ALS then the person sitting across from you or down the hall from you right now take in these statistics they are FAR MORE GREATER and can occur ANYTIME in our daily life giving us a 99.9% chance of it happening.WARNING!!!! If your get scared easy bypass this link. Seriously if we cant lighten up after seeing these causes its time to re evaluate your life and your priorities.
