I find this kind of death exceptionally sad and disturbing. A relatively young and apparently healthy woman with a medical ticking time bomb lurking within her. It very well could have been undiagnosed and she had no idea she could potentially drop dead at any moment.

That's assuming the video's description is accurate and she did in fact die and not simply faint. Given how long she laid on the floor unmoving afterward, I'd say it was sadly the former.
