The 5 elements of life

Chinese have the philosophy that life is composed of 5 elements.  What are they?
The metal, the wood, the water, the fire and the earth are existing in our lives in various type.

Most of time, they are invisibile.  
Can we sense them? 
Yes, we can feel them unconsciously with our bodies.
