Are they young?
Some are in their 40s, while the one that had multiple, had one in their 50s. I think there is a bit of luck to it as well. I know one who had multiple 'mini strokes' and they didn't even know. They just found out after an MRI years later.
lol - that is lucky - or perhaps it speaks to their starting level ;D
Yeah, I think it was both. They also have a very high tolerance of pain, so that was the reason why they didn't realize. Might have thought it was just heart burn or something.
