Our life depends on our body continuing to function. Kind of a basic truth. Years back, I was interested in meditation as a way to keep track of how my body was doing. Deep breaths, blocking out my thinking, meditative scripts, music, lots of ways to quiet the brain, and listen to the body.
Mostly, being aware of our body involves noticing what in the beginning might be subtle changes. Losing/gaining weight? Yellowed skin? Long-lasting, unexplained pain? Digestive disorders? Skin changes? Breathing difficulties?
For most of us, we'd just as soon not have to think about something going wrong. Reality is-- the earlier we recognize a symptom is significant, the more likely it can be fixed.
Many people depend on yearly checkups, mammograms, colonoscopies, and other tests in the doctor's office that might find a problem before symptoms.
There happen to be home tools that can help our body talk back to us. For young folks, this may not be an issue as there are years when we don't worry about things going wrong. The older we get, the more that changes.
