Conventional wisdom says that hardship can make us old before our time.
In fact, a new study suggests that violence leaves long-term scars on children's bodies — not just in bruises on the skin, but also altering their DNA, causing changes that are equivalent to seven to 10 years of premature aging.
Scientists measured this cellular aging by studying the ends of children's chromosomes, called telomeres, according to Idan Shalev, lead author of a study in today's Molecular Psychiatry.
Several factors have been found to shorten telomeres, including smoking, radiation and psychological stresses such as early life maltreatment and taking care of a chronically ill person.

10. I have PTSD
from early child abuse ( it started before 5 yrs old from what I can remember and yes I can remember) and this makes sense of why I feel 60yrs old to my actual 45.
Thanks for the post.
