As for the other benefits of my daily walks they are:
Physical....I don't know how I lived so many years without walking, but even though I was very sedentary and very overweight, I could not get myself out there on a regular basis. And when I did, it was maybe 10 minutes because my back hurt so much and I was out of breath very quickly. I was in the process of trying to get in the habit of walking every day when I found out I had diabetes. I didn't need any further motivation.

Other physical benefits have been to help with my arthritis and increasing my bone density, improving my breathing, lowering my blood pressure and by losing weight, my knees don't hurt anymore!
Emotionally.....When I reached day 30 of walking, I can't tell you how proud I was of myself! I almost couldn't believe it and by that day I was walking a whole MILE! Remember, I was 61 yrs old when I finally started doing something for my health. I felt shameful during the years before when I KNEW I had to do something, but couldn't stick to any kind of routine or get out of my rut. It sounds crazy, but getting diabetes probably saved my life.
I can start out in the morning in a very poor mood, even feeling depressed, and once I've got my walking shoes on and I'm out the door, I feel better about myself and about the world we live in! I've read that..... "Walking 30 minutes a day boosted the moods in depressed patients faster than antidepressants research by the British Journal of Sports Medicine found. Walking releases endorphins increasing your mood and decreasing pain."
Spiritual.... there's something about nature that calms me and reassures me that I'm not all alone with my problems. Even if you don't have a beautiful place to walk (like I do),
there's still the beauty of the sky, the trees, even the air around you can bring on a feeling of peace and serenity. That's how I felt in CA the few times I was there and I've never forgotten it.
Fortunately, I live right across the street from a nature trail so I've been able to see and hear a variety of wildlife on my walks. The anticipation of getting a glimpse of any of God's creatures has given me the motivation to get out there very early in the mornings when it is especially quiet and peaceful. Perfect time to pray and I've done plenty of that in the last 2 years.

So I guess I wouldn't expect for walking to solve all my problems, but it sure gives me plenty of reasons to keep on doing it! And the #1 reason I will keep on doing it? Taking pictures! :) AND to keep my butt in shape!
