Fat of the Land?

A new Lancet study suggests that more people might benefit by routinuely taking cholesterol-lowering statins throughout their mature years (http://www.bbc.co.uk/news/health-18091708). The intention is to reduce the risk of stroke, coronary heart attacks etc. I am somewhat concerned given the well-documented side effects of these hormones on feeling of lethargy, effectiveness of memory etc. Although it is difficult to motivate people, I still think that dietary and exercise changes would be a beter fix.
