This is true, you never know what to believe and in fact with science thats usually a good thing. We can only go where the data points us. When you have enough data all pointing in the same direction, then thats usually the right way to go. The jury is still out with regards to this, however there is a path for the research to continue to go down. Unfortunately progress takes a while. It's still interesting to watch things unfold IMO. I love discussing it as well.
