I was looking for a cheap scorpion to get my collection started and found one in a pet shop that I went in to fairly often. the name listed was golden desert scorpion, and after being assured that it wasn't dangerous, I bought it. the next day I did a search online to see if there was any info on it, and couldn't find the name.
what I did find was that it has a close resemblance to a species named Parabuthus Granulatus. from what I have read I am concerned, since this species is highly toxic, and was wondering if anyone out there knows the answer to this question.

and everything that are relatives of the conpectiztion
triangle can be made into circle, imprefect one
but what about square?
if everything is round, circle based, it means that time is curved, we can make time machine naturally

basically a circle is popular symbol that symbolize immortality or infifity

so maybe we were born immortal
if we follow the path, curves of black hole, the answers will come to me, as they beckons to me in my dreams,
so, the thing inside the black holes, something that can prove einstien's theory of relativity and newton's theoraziton of gravity wrong...
something faster than light, maybe it is time itself?
*it is uncompeleted *sp* theory of mine...*

I decided to tell him the truth by saying that nobody has ever landed on the moon - especially Americans! Have I done the right thing? Or should I keep letting him believe in these things including the Tooth Fairy and Santa Claus?

I just want to do my best for him.

If you have, what's it like? And also, has anyone ever met an American with common sense? If so, what was it like?

I'll probably get thumbs down as you won't find either on Yahoo Answers.
