Smokers whose family members have had a type of bleeding stroke are six times more likely to suffer the same fate than people without these risk factors, according to a new study.
The stroke type known as an "aneurysmal subarachnoid hemorrhage" -- essentially a burst blood vessel in the brain -- runs in families, note Dr. Daniel Woo and others in the medical journal Neurology, and they wanted to see if smoking added to the hereditary risk.
Their study, funded by the National Institute of Neurological Disorders and Stroke, compared 339 patients with aneurysmal subarachnoid hemorrhage with 1016 "controls" without the condition, matched by age, race and gender

A Story about Obese in USA
The number of obese American adults outweighs the number of those who are merely overweight, according to the latest statistics from the federal government.
Numbers posted by the National Center for Health Statistics show that more than 34 percent of Americans are obese, compared to 32.7 percent who are overweight. It said just under 6 percent are "extremely" obese.
Obesity and overweight are calculated using a formula called body mass index. BMI is equal to weight in kilograms divided by height in meters squared. Someone with a BMI of 25 to 29 is classified as overweight, 30 to 40 counts as obese and people with BMIs of 40 or more are morbidly obese.
Being overweight or obese raises the risk of heart disease, diabetes, some cancers, arthritis and other conditions.

Playing Computer Game may Heal Trauma
Playing Tetris immediately after traumatic events appears to reduce flashbacks that plague sufferers of post-traumatic stress disorder, according to a British study. The question is, can the traumatic victims be lead to tetris? It still needs care and love from people for the first aid.
The preliminary findings could lead to new treatments to prevent or cut flashbacks that are a hallmark of the condition, also known as PTSD, Oxford University researchers said.
"This is only a first step in showing that this might be a viable approach to preventing post traumatic stress disorder," Emily Holmes, a psychologist who led the study, said.
"This was a pure science experiment about how the mind works from which we can try to understand the bigger picture," Holmes said in a statement.
The game involves manipulating shapes composed of square blocks that fall down the screen to create a horizontal line of blocks without gaps. When a line is created it disappears.
The researchers believe that recognizing the shapes and moving the coloucoloredred building blocks around in the computer game competes with the visions of trauma retained in the sensory part of the brain.
See, it is to "forget" the trauma, not heal it for the first place.
