Partly because I am kinda of the feeling it ought to stay inside where it belongs (just a feeling, not a concious belief), and partly because I know how much it would suck to go and do it. I don't fear needles, but I do apparently have a wee bit too much perception of what goes on inside my veins. When I had to have a blood sample taken I noticed I could feel the damn needle inside my arm as it shifted around, poking things, and I felt the veins in my lower arm (sample was taken at the inner elbow) deflate
I won't say it hurt, but it was extremely uncomfortable, and sitting still, not rubbing my arm and removing the offending object was...hard. For all of the 30 or so seconds that took. Now extrapolate to a 20 min or so session. No thank you! (Yeah yeah, that 'pain' can't compare to what accident victems go through and so on so forth. It doesn't change my reaction to the thought of the ordeal--but like I said, I may go some day).
