Macular Degeneration and Lifestyle
Macular degeneration causes a loss of central vision and makes it difficult to recognize faces and read small print. The macula degenerates with age and severe macular degeneration causes blindness. Treatment is costly and doesn't work very well.

The authors noted a couple of caveats. They studied only white females so we don't know if these results hold true for men or other ethnicities. They also did not evaluate interrelated habits and they did not look at people with high-risk genotypes for AMD. The authors did note, however, that having a family history of AMD did not alter the benefits of a healthy lifestyle.
So here it is...yet another reason to seize the moment and start doing the things that are proven to create better health as we age. So far I haven't found even one study that did not extol the benefits of diet and exercise and not smoking in creating good health.
