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

Scientists believe that every time the human genome duplicates itself there are around 100 new mutations. They’re pretty common, and usually negligible. However, it would stand to reason that within the pantheon of human mutations, some would express themselves in the form of extraordinary superhuman abilities.

In our life now, there are a lot of elders who have cancer genetics, so I think it can maybe change the gene before they are still an embryo. This process usually involves analyzing human embryos to identify genes associated with the disease, and selecting embryos that have the desired genetic makeup — a process known as a preimplantation genetic diagnosis.

So, is this a bad idea? One specific concern is the possibility for GMOs to negatively affect human health. This could result from differences in nutritional content, allergic response, or undesired side effects such as toxicity, organ damage, or gene transfer.

To sum up this topic with my opinion, those are the reason for this topic.
