This. So much this.What they're doing for a living is irrelevant, because they know no more about Hawkeye or equivalent than anyone on this forum. Kallis should be embarrassed at his comments when he can't even be bothered to go and find out about the system.
On one hand you have Shrek quoting random percentages off the top of his head - the same one that has hairs implanted into it after years of scientific research so he could look less like a tit. On the other you have scientists who've been doing this for years and the fact that they've got such a system in place at all should tell you they know what they're doing.
Now who am I going to back? I'm amazed at people can even debate this.
This is scientifically researched. If you want to question this on a scientific level then by all means. But you're just talking complete **** like Kallis. Making it up as you go along. How the hell you can go on like you or him know more about this than the scientists who developed it is unbelievable. It's this sort of thinking that means we get people going to a witch doctor instead of a medical scientist. It's an argument of blind faith against science. For whatever reason something in your head tells you to be perverse just for the hell of it.
