I am trying to destroy several boxes of old financial statements. Too many to shred and I don't have an easy/safe way to burn them. A liquid shredder/dissolver might be just the ticket.

Alright we appeared here on earth. I do think theres a god, but a number of times Ive argued with people over who god is.

God could have been an alien or alien race that sent our DNA to planets they terraformed and we grew? Anyways its an idea :P

Thoughts?

Albert Einstein said that if we get the speed of light,we will be able to travel in future..

or by another saying we can travel in past life,

i believe that it mat be possible to go in past life,but in past life we will not be able to take part in any activity & not be able to change any condition...

and i dont think we can be able to travel in future which has not occured ,although we get speed of light..

frnds what do u think??
