My ACE score is 9 too!
You've made it to 50

The higher likelihood of early death is due to the increased likelihood of traumatised people to smoke cigarettes, self medicate with drugs or alcohol, over eat or under eat, experience suicidality, be too 'triggered', dissociative, depressed, anxious or agoraphobic to work/earn money/pay for good nutrition, etc. All lifestyle factors. Decreased self care is the cause of early death.
Also, untreated CPTSD keeps our bodies extremely hypervigilant, pumping out endless cortisol and stress hormones, which taxes our organs over time.
We can do things about all of the above factors.
As mentioned, resilience scores are also important.
