When I was a kid a Russain a scientist said we can pass on experience to our children. This was proposterous in American scientific circles. Now due to epigenetics certain protiens that are found to turn certain genes on or off in relation to life experiences. One day we will learn to fold certain protiens to turn certain remarkable abilities on or off.
Trauma is one of those epigenetic factors that can get passed on in families where every generation is expected to serve. I don't know if that can be a minus or plus.
