Every body has hearts, lungs - these are similar but not the same in all - depends on age, health, genes, and other factors.
It is the same thing with the chakras - they are similar, not same. The Chakras audio/tag will benefit anyone as we all have some form of this energetic structure called Chakras. I have seen differences in chakras, but yet to see anyone not having them (at least the humans I have encountered 
)
