Ultra sound says peak velocity involving the right common carotid artery is equal to 82cm/sec says mild atherosclerosis 41 male is this normal ?

It is NOT normal but it is not uncommon at all for Americans at your age. So if you have modifiable risk factors for atherosclerotic vascular disease such as smoking, hypertension and hyperlipidemia, you need to tackle them for delaying the progression. Good luck.

Athersclersclerosis is never normal. It is not a part of being human unless you fail to feed/exercise your genes. Lok at you family tree for how often and age its occurs and consider changing how you feed/exercise you roots.
