Ignorant men always think they can play god and have power over nature
such men have unleashed many Artificial genetic diseases which were nonexistent 100 years back and now they are again fooling us by selling us the cure for the problem they have created, first they fooled around with atoms and now they want to fool around with genes, nature has created us PERFECT.
A Caterpillar does not require scientists help to transform into a butterfly it is already designed in its DNA

Humans are not meant to advance the physical body by artificial means the body is eventually going to perish no matter how advance body you develop.

Humans are given this body to realize that they are not this material body but the eternal soul, its is the soul that is suppose to evolve by having this human experience.

Anything Material in this world is of temporary existence all your efforts will be fruitless because there will always be something you unable to figure out.

Stop messing around with the human immune system you will only spoil it, and start researching about the soul it will change your life.
