It’s important to keep your cholesterol levels within healthy limits. Whatever it takes – diet, fitness, drugs – drop your total cholesterol below two bills. With every one percent reduction of total blood cholesterol, there is about a two percent reduction in the risk of heart attack. So bringing down moderately high cholesterol (up to 239) will buy you an extra six months, according to research. And if your level is in the 300+ range, dropping down to 200 can extend your life by more than four years.
