Is your memory your own?

The other day I was talking to someone about brain transplants. We were discussing if someone, one day, could have a brain transplant, what would happen to their memories, and would they take on the other person's memories and knowledge as their own? For instance, if a man got a woman's brain, or an english speaker got the brain of a spanish speaker, if a child got the brain of an elderly person, etc. what would be transferred and what would be forgotten? Or perhaps would it be wiped clean with no recollection of anything including a transplant. Obviously, brain transplants are not possible with today's technology and medicine, but one day, it would be interesting to see how it turns out.

Aliens Exist...or do they?

I read The Host by Stephenie Meyer a long time ago, but I was just thinking about it the other day, because I'm hoping someone will make it into a movie soon. Anyways, in the book, souls are taking over human bodies and the humans are trying to survive. It was a really good book and I highly reccomend it. Another novel I read more recently, I am Number Four by Pittacus Lore, also deals with alternate life forms from other planet systems. Anyways, while I personally don't believe in aliens, to me it is still a very entertaining idea and makes for good novels. :)
