A new study found that more active seniors lowered their risk of developing severe age-related macular degeneration by as much as 70%.

Researchers at the University of Wisconsin's School of Medicine and Public
Health also found that people who walked regularly, about 12 blocks a day,
were 30% less likely to develop wet AMD, the type most commonly linked to
serious vision loss. Nearly 3,900 men and women age 43 to 86 participated in
the study over 15 years.

While researchers note that other factors, including diet may contribute to
the findings, physical activity is known to reduce inflammation, which is
thought to contribute to the development of AMD.

The report was published online in the British Journal of Ophthalmology.
