Once we get to a certain age, there are certain things that we should not let slip by without checking out. If you think you may have had a symptom, I suggest a trip to the doctor for a full physical.
Things that should be checked on a regular basis include a prostate exam, blood pressure, cholesteral, triglycerides, stress test and other precautionary measures that your doctor might suggest. As I'm sure you're aware, early detection is the key to prevention. Check what you can now, before a traumatic event occurs.
