I own more than 100 DVDs or Blu-Rays.
Not by myself I think, but if I combine with either of my parents I do, which I don't count as mine so that's a no.

I have never read a novel written by Charles Dickens or Jane Austin.
Why?

I've fired a gun
Went to a range once, it was fun, would have gone again this summer if I wasn't sick at the time.

I have been in both the northern and southern hemisphere.
I haven't and don't particularly want to go to any of the countries in the southern hemisphere.

I like to sun tan.
It's meh, if I do I like to not put any oil on and flip me like a burger.

Over the course of my adult life I have voted for at least two different political parties.
Same as Ari actually.

I have had either my tonsills or my appendix removed.
Don't think so (: let me check.

I have at least one (what I consider to be a) major allergy to something.
Nah, superior gene pool here :D

I have donated blood.
I haven't gotten myself to go, maybe I should.

I believe in ghosts
pfft.
