If you want to stay out of a nursing home as you get older, you might want to stop smoking and start exercising now. In a new study presented at the International Conference on Obesity, researchers at the University of Sydney analyzed data on over 127,000 Australians. They divided the participants into three groups based on lifestyle factors, including smoking, physical activity, sitting, sleep quality and diet quality. They found that those with the least healthy lifestyles were twice as likely to be admitted to a nursing home. In fact, smokers had a 55 percent higher chance of needing nursing home care than non-smokers.
