Many of us equate feeling good with being healthy, lulling ourselves into a false sense of security. After all, we often hear of people who have never complained of being sick yet they die suddenly. This is often the case with many whose lives end with a heart attack without the slightest tell-tale signs that could have warned of what was to come. So while we all strive to feel good, this should not be taken to mean we have a clean bill of health.
