How can someone knows how old are his arteries, for example:if i am 37 years old, how do i detect how old my arteries age, any method i can follow?

Arteries are ur age: Arterial duplex can assess segments of some arteries for arteriosclerotic plaque formation. Even if no plaque visualized, the artery may have early plaque or yellow streaks which is arteriosclerotic disease. If you image the carotids in the neck, you can still have carotid disease in the intrathoracic or the intracranial segments of the artery. So even if the neck portion isokyoucanstillhavestroke.
