Apparently you can get your telemere length measured and know exactly when you will go ( though lifestyle changes might lengthen them again ) _ I am considering getting it done because my PTSD is a work injury and if I can prove I have less telemere length alongside what the reseach says about losing ten years life expectancy maybe they will have to pay me for my anticipated lost years .....changing diet may cut down in inflammation but I suspect that some of our issues are about genes being switched on or off and we might be damned no matter what we do. I think for adult induced PTSD they estimate ten years of life lost.
