Grief Is Constant for Many Directly Affected by 9/11 Attacks

Many student loan calculator people directly affected by the 9/11 terrorist attacks still suffer constant grief, says an American Red Cross survey released Friday.

Nearly two-thirds of the 1,500 emergency responders, survivors and victims’ relatives who took part in the survey believe that grief still interferes to a moderate or large extent in their lives, The New York Times reported.

Just over 40 percent said they still need additional services to help them recover — including mental health services, financial assistance, and medical services.

Uniformed responders and people closest to the recovery efforts have been most affected by mental distress, the survey found. This link between mental health problems and proximity to the attacks was noted in a recently published study on survivors, the Times reported.

Cheaper Cigarettes Entice Young Adults to Smoke: Study

Lower cigarette prices mean that more young adults, ages 20 to 24, are likely to start smoking, says a Canadian study that looked at the impact of tobacco tax cuts.

For a number of years, the Canadian government and several provinces increased tobacco taxes to discourage smoking.

The tax cuts in the five provinces ranged from $14 to $21 (Canadian) per carton.

In provinces with the tobacco tax cuts, 10.5 percent of young people started smoking, compared with 8.5 percent in provinces that didn’t lower their tobacco taxes, the study said.

The findings, which appear in the current issue of the American Journal of Preventive Medicine, suggest that tobacco price hikes could be used to counter tobacco advertising that targets people in their 20s.

Two more people in Indonesia have been killed by bird flu, according to preliminary test results.

The latest victims were an 18-year-old boy and his 10-year-old sister from West Java. They died Tuesday within a few hours of each other less than a day after they were admitted to hospital in the city of Bandung, the Associated Press reported.

Initial tests showed that the two were infected with the H5N1 virus. The tests will be sent to a World Health Organization (WHO) laboratory for confirmation. To date, the WHO has confirmed 33 human deaths from bird flu in Indonesia and 124 deaths worldwide.

The two latest deaths come as experts continue to investigate a bird flu outbreak involving at least seven members of a family in the village of Kubu Sembelang in northern Sumatra, Indonesia. Six of the family members died.

WHO officials said the cluster appears to be a case of limited human-to-human transmission of the H5N1 virus, the AP reported. All the family members were blood relatives who had close contact with each other.

On Thursday, WHO officials said the family cluster appears to have originated with one woman who then passed the infection to relatives. “We believe she may have had some contact either with dead or dying chickens in her household or through her activities as a vegetable grower and a seller in a market,” Steven Bjorge, a
