Mind transfer

Mind transfer or mind uploading is the process of a transferring ones local mind (the part located within the brain) to an external carrier such as a computer.

The process of tranfering ones mind into an external carrier is very difficult to do since it requires highly advanced technology and a fully focused mind.

During the stage of the process where your mind is getting transferred to another host the original personalities body can sometimes die or worse crumble to dust.

Mind transfer gives you a form of immortality which is limited at best but unlimited at best:

to give an example of how someone could attain a form of immortality through mind transfer he'res a scenario of someone doing just that. As you can see mind transfer can be useful but it doesn't provide you with full on immortality since your mind could be destroyed in the process giving you temporal immortality at best.
 * 1) Person "a" is dying at the age of 125 so they decide to transfer there mind to the body of a 45 year old who has another 90 years to live before they die, this gives person "a" a lifespan of 215.
 * 2) When this body fails person "a" transfers there mind to a 200 year old who has another 133 years to live, this gives person "a" a lifespan of 348.
 * 3) Person "a" continues doing this for thousands of repetitions until after millions of years he attains the ability to transfer into literally anything from stars to the fabric of the universe itself.
 * 4) This would allow him to live until the universe decays into the quantum sea it came from resulting in person "a's" mind being lost in a sea of probability and randomness.

It can also be very risky due to the possible interference from the other persons mind if they are a stronger mind transferer than the person who is trying to pocess them.

Besides from this and other reasons why mind transfer is sort of terrible there are an equal number of reasons to do it.
