Hope

Holding on to hope may not make patients happier as they deal with chronic illness or diseases, according to a new study by University of Michigan Health System researchers.
"Hope is an important part of happiness," said Peter A Ubel M. D, director of the U-M Center for Behavioral and Decision Sciences in Medicine and one of the authors of the happily hopeless study, "but there’s a dark side of hope. Sometimes, if hope makes people put off getting on with their life, it can get in the way of happiness. "
The results showed that people do not adapt well to situations if they are believed to be short-term.

"Our research shows that the hormones of pregnancy are protecting the brain, including estrogen, which we know has many neuroprotective effects, " Kinsley said.
"It’s rat data but humans are mammals just like these animals are mammals, " he added in a telephone interview. "They go through pregnancy and hormonal changes. "
