I can understand getting rid of defects, susceptibility to diseases or genetic conditions, etc. I can even see getting rid of some bad genes that dont cause disease but which are harmful....eg soft tooth enamel which runs in my family.
Im a lot more leery of improvements. What if a boy is going to grow to a max height of 52 and by tweaking something you can change that to 510? I have no doubt that would help him with women, with job prospects etc. it would enhance his quality of life. Where does it stop though?
So we have you down as saying outright... that you only advocate a little bit of eugenics.
I'm NOT overweight ... I'm under-tall!
