I'm 62, and after being diagnosed with "high cholesterol about 12 years ago, I've been on simvastatin (20mg). This has always been an entirely "preventative" measure. No heart disease, I'm skinny (120lbs), don't smoke, hardly drink. Get exercize. I'd love to stop taking the statin given the data on possible muscle damage and cognitive issues.
Without taking the statin my recent numbers are HDL 63, LDL 152, overall 235, with a ratio of 3.7.
