What would you genetically change about humans to make them a better species?

Human germline engineering is a type of genetic modification that directly manipulates the genome using molecular engineering techniques. Aside from germline engineering, genetic modification can be applied in another way, somatic genetic modification.There are many diseases in the world. A disease is an abnormal life activity process that occurs due to the disorder of homeostasis under the destructive action of a certain reason. It is a specific abnormal pathological phenomenon, and it will affect some or all organs of the organism.At some point in the near future, quite possibly within the lifetime of those now living, we will have mastered our own genetic code, and perfected the means to manipulate it.So I don’t support genetic modification.The dangers are greater and closer than they appear, but the potentials are greater than human aspirations.
