I am a 53 y.o. female weighing about 58 kgs. I eat a healthy diet, very little fat or dairy products, walk most days 20-45 minutes fast up hill and down. I have had high cholesterol for about 30 years. Tests from one week ago show 273 (HDL 64 and LDL 181). I believe in my case it is from my mother, who always had very high cholesterol. My questions is, if ones high cholesterol is genetic, is it still as dangerous as if it was caused by my lifestyle? Many thanks in advance. Glenne
