People DO die from MS BUT it is VERY rare.
(think ~ Marburg variant, something you would be tested for and know if you were having a fast hard course of MS)

People die from complications due to MS.
(think ~ skin breakdown and ensuing infection, etc.)

Most people LIVE WITH MS.
( think ~ that would be most of us here)

Regardless of what she died from, she was a living organ donor and that makes her a hero in my book ~ just like our DM!
