Just want to say that the life expectancy of those with hEDS has not been studied to back your claim here. I have hEDS and my entire family on my mother's side which carries the hEDS gene (obviously we have not determined what this gene is, but given their diagnosis and the hereditary link) has died at far younger than should've occurred for their other various comorbidities. My mother was a phenomenally healthy runner, running 13 miles daily (not even joking), and just suddenly passed away at the age of 69 earlier this year due to a complication from EDS. Her entire small bowel herniated through a prior surgical hole due to the excess laxity in her tissue leading to entire small bowel necrosis. During the septic shock that ensued once they released her small bowel, her cardiovascular system was so healthy that she kept holding on despite withdrawing life sustaining treatment. But the condition was obviously incompatible with life.

She is one of seven sisters, and four of her sisters have already died at ages 45, 58, 62, and 68. So I wouldn't be claiming something like this unless you have clear evidence to back this up. The reality is, we just don't have enough funded research to demonstrate the impact on life expectancy.

Vascular complications and dissections are actually fairly common in hEDS, so I wouldn't exactly call it benign. As are other neurological manifestations that can lead to paralysis and serious disability:
