The perfect storm

The more that I learn about the autoimmune condition called Multiple Sclerosis, the more that I'm certain of my conclusion.
1. Everyone who I have come in contact with that has MS was uncommonly active before the diagnosis.
2.  They each had a stressor in their life and
3.  They had certain genetic factors present.
It was as if the "perfect storm" of conditions made the disease present itself. It's as if we "pushed the disease out" and forced it to show itself.
