als hi diza re your edit on amyotrophic lateral sclerosis i just wanted to let you know that this is a discussion that's been had before the logic in calling it fatal is that for the vast vast majority of patients it is unfortunately a rapidly progressive disease although about or so survive past years most do not i would certainly agree that primary lateral sclerosis or even progressive muscular atrophy could be considered chronic rather than fatal although the latter is also life limiting as a counter example i would say parkinson's disease is chronic rather than fatal even though statistically people with the disease do live for a shorter time than those who do not have it interested in your view
