This is going to be short and sweet.
How can anyone think it is a good idea to take an entire generation of human beings and irreversibly and unnaturally alter their metabolism in this way?
Will it create a generation of women who have serious fertility problems, as adipose tissue is important for childbearing? A generation of people with possible neurological and cognitive dysfunction? A generation of people who, in the event of a large-scale food crisis, have no reserves on which to rely? How young will they be when they develop osteoporosis? Will they all need c-sections, since they won't have enough adipose tissue to produce hormones vital to the birthing process? Are they going to move to the southern states because they'll be cold all the time? Will we have enough orthopedic surgeons to replace all their broken hips? If they get cancer or heart disease, will they die at higher rates than the previous three generations?
If anyone is actually trying to make the case that this would be for health purposes rather than aesthetic purposes, that person is an obtuse, short-sighted idiot who needs a few whacks of a clue-by-four.
Edit: Just saw some utter coolness--my vet is one of the Google ads today! Parkside Vet in Albany--they're really nice!
