THIS is very interesting (pointed out by Surreal on SCmkII).

'Although children in rich and poor households have very similar sets of genes, the scale of adversity at home dictates which combinations of those genes are switched on or silenced through a process called epigenesis – presumably to maximise the chance of survival. "They may be protective responses, and the payoff is surviving a threatening childhood," says Marcus Pembrey from the University of Bristol, UK, who co-authored the study whilst working at University College London's Institute of Child Health. The penalty might be activation of genes that make poorer people more prone to heart disease, diabetes, cancer and other diseases. That could help explain why poorer people often have shorter lives. Epigenetic changes have also recently been linked to conditions that can involve psychosis, including schizophrenia and bipolar disorder.'

"This could cause alterations that blind people to external signals or make them more sensitive to them, he says. Such changes could make people unusually sensitive to threatening situations – useful if they encounter such situations regularly during childhood."

I want to ask for thoughts about improving the world -- what do people need? How can things be organised?
