Another Plus for Exercise

Exercise For Your Eyes

This Forbes article discusses a finding that exercise can reduce age-related macular degeneration by 70%. While they point out that this is merely correlation (which does not equal causation), it is a salient finding. Exercise improves your skin and muscularity, lowers your blood pressure, regulates your bodyweight, and releases endorphins that make you feel good. Exercise also reduces your risk of heart disease, colon and breast cancer, diabetes, and depression. It's good for so many things, why not your eyes too. A sedentary lifestyle is at odds with our genetic heritage - only in the late 20th century did humans become largely sedentary and we are paying the price with our life.

You don't have to go out and run marathons or deadlift small automobiles. Even walking, while it's not going to get you into great shape, is better than nothing. Throw in some resistance training and you can build some muscle at the same time. CrossFit is an excellent exercise program that is scalable for all ages. There are people as old as 70 and as young as 12 on CrossFit. Whatever you do, do something.
