Question: Midichlorian's are chemical compounds found within every living cell that forms the basis between the connection life and the Force. Without midichlorians, life would be impossible. The amount of midichlorians in a life form represents its ability to understand, comprehend, and manipulate the Force.

My name is Darth Incognitus, and I have decided to absorb more of these cells into my own body to make my force sensitive abilities stronger. To accomplish this, I have kidnapped numerous force sensitive users who match my blood type. When their midichlorian count has been measured, I will perform a blood transfusion from them to myself in order to absorb these cells. After I have attained enough of these cells, I will become the most powerful force user in the world and create my Sith empire. Then, I will use this method to strengthen my apprentices and students.

However, after a number of tries, I have noticed that my powers have not increased. No matter how many Jedi I murder and drain of blood, my abilities remain average. Why would this be the case?

Answer: 
### [Homeostasis](https://en.wikipedia.org/wiki/Homeostasis). Your body maintains an equilibrium, like blood or temperature

A normal human has around 5 litres of blood in their body. If you transfer a litter of to your body (and not die), would now you have 6 litres? Well... maybe, but not for much longer.

Or temperature, you are at 36℃, if you increase/decreases your body heat from your surrounding, will it stay in that forever? Of your not. Your body maintains a level of temperature, by warming up or cooling down at certain thresholds.

Your blood amount is also determined by your body, not your blood transfusions, if you have a lack of blood, your body will produce more to compensate it, and if you have too much, your body will dispatch the blood's water from kidneys, and **red** cells' will be recycled into [bilirubin](https://en.wikipedia.org/wiki/Bilirubin) (**yellow**) in the spleen and that dispatched from duodenum as [stercobilin](https://en.wikipedia.org/wiki/Stercobilin) (**brown**). Interesting transformation of colours, right?

Midichlorians are like blood, and a lot more things in our body, like hair, adipose tissue, temperature, etc. A transfusion may only increase the Midichlorians during a very short time (if the body is able in the first place to take advantage of them and don't die/get sick due an increased level), then the additional amount will be quickly destroyed/dispatch/recycled by your own body...

...Or maybe not, they aren't destroyed, but anyways they have a certain lifespan, so if you transfuse them to your body, they will work in you until they "get old" and die, like red cells (120 days). Then you should transfer more from the original source... or steal their Midichlorians's stem cells. **That is up to you**.
Midichlorians act as a mediator between the Force, the mind, and the body, all three acting in concert. Because of this, **midichlorians aren't just sensitive to the force, but to the unique pecularities of each person's body chemistry and bioelectric field**. These things change over time, of course, but it happens slowly enough that the organs which produce midichlorians can adapt as a person grows.

**The shock of being suddenly removed from one body and transplanted into another is too quick for the midichlorians to adapt**. Given enough time, they would indeed "learn" how to work with another person's body and mind, as theory might state. The problem is preventing the body from rejecting and excreting them before that happens: it just plain takes too long. This is not something your sith has mastered.
