Normal Blood Sugar Levels - Real Life Experience

If anybody raises the question "What are normal blood sugar levels?", the answer is simply beating the same track repeatedly. From a diabetes blood sugar levels chart, it is read that the normal blood sugar readings are 70 - 100 mgs as fasting blood sugar levels and 100 - 140 mgs as random. However, type 2 diabetes blood sugar levels are not within these limits with blood sugar sensitivity. But anyhow it is not exclusive since there are some factors of normal blood sugar levels - hypoglycemia and hyperglycemia.
