High calcium in the arteries in not the all due to the 'aging process'. Yes as people get older 'some' and probably will get some degree of calcium in their arteries. I know people in their late 60s with scores of 0, and teenagers with scores over 100. Genetic disposition, lifestyle factors, diet, vascular injury, inflammation, and repair all play a huge role beyond aging. It is present in 90% of men and 67% of women older than the age of 70, thus it leave the rest of those older folks with none.
