According to Star Wars lore, midi-chlorians are the microscopic entities which reside within living creatures and essentially act as a vector for the Force. They can be detected in blood, and have been linked to how powerful any Force user can be; the more midi-chlorians, the greater the power. This video expands upon it:
It has been inferred that high midi-chlorian count doesn't necessarily equate to over all greater Force power... just as genes don't essentially dictate a child's exact capabilities, so much so as their potential for it (Micheal Jordan's kids, even possessing his genes, won't necessarily have his same design which was suited for basketball, or his talent for example.)
However, its also been inferred that Force powers can be improved by practice and training, and not just like "skill building"... as in becoming so adept with knife throwing in focus, aim and neuro-muscular action that after a year one can fire off knives repeatedly, more quickly and with an aim that can more accurately hit targets... No. The implication is that Force powers can be improved by actually getting stronger, like a muscle being able to lift more and more weight after continuous resistance training.
Does this happen because the midi-chlorian count increases, or the user's skill with the exact same number increases?
Is there some way to "disrupt" midi-chlorian connection to the user to remove their Force powers?
And why are Force powers somehow stronger in certain areas than others? Is this because the midi-chlorians themselves are being "charged" some way, or increasing in number?
