Walking Speed Predicts Life Span

Walking Speed Predicts Life Span - Stephanie Studenski of the University of Pittsburgh, and colleagues conducted a study to assess the association of gait speed with survival in older adults and to determine the degree to which gait speed explains variability in survival after accounting for age and sex.

The study included a pooled analysis of 9 participating studies (collected between 1986 and 2000), using individual data from 34,485 community-dwelling adults age 65 years or older with walking speed data available at the beginning of the study, followed up for 6 to 21 years.

During the course of the study, there were 17,528 deaths. The overall 5-year survival rate was 84.8 per cent; the 10-year survival rate was 59.7 per cent.

The researchers found that gait speed was associated with differences in the probability of survival at all ages in both sexes, but was especially informative after age 75 years.

At this age, predicted 10-year survival across the range of gait speeds ranged from 19 percent to 87 per cent in men and from 35 per cent to 91 per cent in women.

Man Hits Teen on Plane Over iPhone

Man Hits Teen on Plane Over iPhone - Police say a man on a Southwest Airlines flight from Las Vegas punched a teenager who refused to turn off his iPhone as the plane approached the Boise airport. Officers arrested 68-year-old Russell E. Miller, of Boise, on suspicion of misdemeanor battery Tuesday. He has been released from jail on bond. Witnesses told police the 15-year-old was playing games and listening to music on his cell phone when flight attendants instructed passengers to turn off their electronic devices because the plane was landing. Witnesses told police that when the teen didn't respond, Miller got angry and punched the boy in the arm. Miller says he "tapped" the teen on the shoulder after he refused to turn off the phone. He told the Idaho Statesman that he may have "overreacted," but that he did not punch the teen. Man Hits Teen on Plane Over iPhone

Contactless Debit Cards

Contactless Debit Cards - Contactless debit cards will make their formal debut in Canada next year with the launch of Interac Flash from Acxsys Corp.’s Interac Association, Canada’s national debit network. Interac’s first two Flash issuers are Scotiabank and RBC Royal Bank, which will roll out their first contactless cards next summer. The first acquirer is TD Merchant Services, a unit of Toronto-Dominion Bank. More issuers and acquirers are on the way, an Interac spokesperson tells Digital Transactions News, though no announcements have been made yet. Interac and the banks tested Flash this summer at some high-volume, small-ticket merchants in downtown Toronto. The spokesperson expects national merchants will be making formal announcements about acceptance. “There’s a lot of excitement in the merchant community,” she says. “Merchants are looking for that faster throughput.” In a statement, the Retail Council of Canada endorsed the new card. “Interac Flash is a welcome and needed ...
