Animals run everyday and they're still alive.
Animals can also synthesize their own Vitamin C, similar to how humans can synthesize Vitamin D through sunlight on our skin and a metabolic process involving cholesterol. Animal physiology isn't always paralleled by human physiology.
I've said this before;if you want a full body work-put swimmimg of even mountain climbing will do it better than walking.
Edit:Depending on your age;your knees will most likely give-out before your heart will.

Uhh.. can anyone explain this?
Many sportsmen are struck down in their youth due to the heart-related problems. Tremendous levels of physical activity force the heart of a sportsman to work like a pump, which leads to partially irreversible left ventricular hypertrophy with impaired left ventricular diastolic filling.
Hypertrophy? Yes. That just means an enlarged left ventricle, which is fine as long as it is vascularized properly. Impaired diastolic filling? I have not read this before. I'm not sure what I think about www.anti-aging.com in general, though. On the other hand, it is fairly irrelevant unless you're planning on becoming a professional marathon runner or some such.

Well, I had thought regular cardio and such will increase the strength and endurance of your heart; and thus also making it bigger. Which most sources have told me it was a good thing; correct me if I'm wrong. Though... is it possible for the heart to be too big?
Anyway, in the article, it seems to 'condemn' the enlargment (hypertrophy) on the heart...
As for this impaired diastolic filling, I haven't heard of it before either, well not because of "Tremendous levels of physical activity". If anything, I've heard that such cardio will even increase diastolic filling.
Ugh, I dont like this medical stuff. Endless number of articles each contradicting each other. -_-
