It's terrible. Interesting how in some it progresses slowly - Steven Hawking lived with it for 50+ years, but the average expectancy is 2-5. My BIL passed from ALS in 2013.had a teacher in 4th grade, also she was a friend of my mom, had ALS. She lived with it for 30 years. It progressed very slow. It ended up getting severely bad. Very sad disease. Wish the could figure something out to at least help out. I realize it's probably not something they will every cure though.
