Do your perhaps remember the grandparent with whom you did not have to say a word but felt perfectly loved and accepted? Or do you remember the friend who could provide soothing balm with his sheer presence?  

These are all people who through their energies bring a sense of well-being to others. They may not do it consciously but deep within them are ingrained habits of positive and encouraging thoughts. 

Now can you remember a co-worker who walks into the room and everyone wants to walk out?

Even though they work on energetic meridians that only a few people can see, acupuncture and acupressure have long been accepted as techniques that create tangible results in the physical body.  Their results have been so impressive that many insurance companies reimburse such treatments, even though they defy the standard medical understanding of how the human body works. 
The reason that these techniques work is that acupuncture and acupressure practitioners use the physical body to access the energy body and shift energy there.
