The thing with epigenetics is studying holocaust survivors and their descendants have added hugely to the sum total of knowledge we have about human genes.
Howevver, it has also brought into sharp focus the many different ways jews born decades later are still suffering the effects.
I am the daughter of a daughter of a holocaust survivor, and have been involved in these studies. My unusual sleep patterns , and those of my mother ( more so) and my daughter ( less so) have been scrutinised.
I am told that we are a very clear example of a after affect of severe trauma in an ancestor in the female line, and these effects last three generations, as far as we know, but any children my daughter has will be part of the same study.
So, yes, it is good to understand why I sleep so erratically ( 2 hours on, 2 hours off last night, fairly typical)
however, it does keep the whole issue constantly in my mind, because it crosses my mind most nights, when I am up and about.
Other epigenetic affects in other families are more difficult to live with, and the social effects are with us all the time too, it is traditional to name new babies after dead relatives, for example, but the list of dead relatives to be remembered in my family will be supplied by the holocaust for some time yet.... a bone marrow transplant was looked for last year, but the individual needing it was an orphan adopted from a concentration camp, and has no known blood relatives..... and always at funerals, the minister asks for date of birth, place of birth, etc of the deceased and more often than not, we just don't know.
So yes, the holocaust is in the fore front of people's mind. You might say it is to an unhealthy extent, but for the most part we just live with it and get on with it.
I'm not sure how we could stop thinking about it, to be honest.
