I have selective math phobia. Never found too much interest in fundamental mathematics.
Other science subject were a lot more intuitive for me... so I headed off into that direction. After a while you forget stuff. The process of sitting down and trying to follow/figure things out from textbook again I found to be too time consuming. If you don't have the background, you can't exactly move onto other stuff.
So lack of interest & practice is why I avoid calculus, physics etc... basic statistics though I use on daily basis.
