Not exactly gasorg, I am fascinated by severe weather and have a passion for it... and I don't even know how to play a musical instrument.
But I am a computer geek

.
As for the fear thing... With me its kind of both. There was once in 2004 May 30, an F0 tornado touches down in my city. I wasn't really even scared at that point.... just more fascinated than anything else. Kind of that "hypontized" effect.
But this year when I chased what I thought was a spin up tornado... turns out to be a gustnado (I am still learning). I was scared. But I was scared because I felt I was too close to it. My first instinct was to run and get away... but I held back and waited to see where it was going to go. The circulation that formed vanished as fast as it formed, but it moved just north east of me. I felt it was too dangerous to follow because I couldn't see and I was mainly worried about the power lines and turned around heading further south then east trying to catch back up with it. But it already moved on, but again I just chalked it up as a learning experience. Got some pretty wicked photos of cloud formations

But we got mostly rain than anything else, even though there was a confirmed EF-1 tornado 12 miles west of me just 15 mins prior to that. Then again I live in a valley so my delays mainly due to safety (avoiding hills).
I would agree with several others... about having the passion part. There are times where I felt like giving up chasing forever and a while where I didn't think about it.. (3-4 months). Then had another round of severe weather come through and I was hooked again. I even tried finding other things to do... I just keep coming back to it. Its kind of like my passion and curse at the same time.
