Don't be worried about your cholesterol reading as it is meaningless. Cholesterol rises steadily with age and studies have demonstrated that we live longer if this continues into old age. So to fix any figure as a norm for everyone is ridiculous, just as it is to insist that it be lowered.
Also any one-off reading is meaningless as it depends entirely on what you were doing or feeling in the minutes before the blood test was done. For example: if you ran to the surgery it will be higher than if you walked; if you stood in the waiting room, it will be higher than if you sat; and if you were worried about the test, or your doctor looked worried, it will also be higher. This is because a raised cholesterol is part of the 'fight-or-flight' reflex.
The other thing that wil be discussed is the relationship between LDL and HDL, the former being 'bad' and the latter 'good'. Again this is nonsense. Cholesterol is not water soluble, so it is transported around the body in packets containing other nutrients. The packets are called "lipoproteins" (lipids + proteins) -- the last letter in both of the abbreviations. Cholesterol is a major building block in cell repair and regeneration, a process that is going on all the time. It is carried around the body from the liver to where it is needed by LDL; the used cholesterol from older cells is transported back to the liver for recycling by HDL. To put it in terms of house renovation, LDL is the truck bringing new bricks to the building site and HDL is the skip taking old materials away for recycling. There are no 'good' or 'bad' lipoproteins or cholesterol, they are both essential.
One other point: Your body isn't in the habit of making things that are harmful to itself. If it wants 8.1 mmols swishing around each litre of your bloodstream, then it's a good idea to let it get on with its job. It seems that the biggest risk factor of all is mucking about with your body unnaturally.
Statins
The next point is more important: The statin studies do show that statins confer small benefits in middle-aged men who have already had one heart attack. But not because of cholesterol-lowering, as the benefits were the same whether cholesterol was lowered a lot or not at all. So it is NOT lowering of cholesterol that is the beneficial action, but something else. Even then the benefits are small.
And secondly, there have been shown to be no benefits in men who haven't had a heart attack, no benefits in the elderly and, significantly for most of this list, no benefits in women of any age whether they have had a heart attack or not. So there is no evidence that Zocor (simvastatin) will benefit you at all.
And lastly, statins have a range of serious side effects. You may have heard a couple of years ago, about one statin, Baycol, being removed from the market because of deaths associated with its use. But all the other statins carry similar risks. The process in the body by which cholesterol is synthesised, and which statins inhibit, is the same pathway that the body uses to make co-enzyme Q10, probably the most important antioxidant. Co-Q10 is also used in large quantity by the heart. It is no coincidence that people taking statins have an increased risk of conjestive heart failure.
And as they lower cholesterol, they also increase cancer risk, particularly from breast cancer.
By the way, a report in the Journal of the American Medical Association, found that doctors were the third leading cause of death in the USA in 1999. (Starfield B. Is US Health Really the Best in the World? JAMA 2000; 284: 483-485). Four years later, another report elevated them into first place (

So, in the USA, doctors are the leading cause of death -- and there is no reason to suppose that doctors in New Zealand, who follow US guidelines, are any better. Bear in mind that it was these people who set the standards for cholesterol -- and who push cholesterol-lowering drugs.
