True, not everyone will agree with the same thing, that's why we are allowed to make our own decisions. Just like when it comes to gasoline, my brother drives a gasoline truck, and has told me some things about his deliveries. As much as I try to convince my friends that sometimes the gas at Chevron is no better than the gas at Diamond Shamrock, it's just the grades are different they don't believe me, I even worked for an oil company and saw the different grades of oil and there lubrication. I know that is off the subject, but it just goes to show that know matter how much somebody knows about a topic, some people are just going to go with what their mind tells them to go with.
Being that petroleum and mineral oil as stated before in the link posted by Jade, are natural products that are not harmful to the environment because they are made by mother nature, it's funny how we still relax or put other chemicals in our head that are mixed up with an abundance of un natural chemicals. I don't see a problem with relaxers or anything like that, it's just ironic, it's almost to me like a person on a diet eating a cheeseburger, fries, and drinking a diet coke.
I've only been a member of the site a few months, I just wanted to be schooled, maybe there was something I needed to know that was dangerous, I guess now I know and have enough info to do my own research, thanks guys!
