Granted; you now cannot ever again remember your name, your fondest memories and what the colour pink looks like.
I wish I could see the extra colour that birds can see. *Without* becoming a bird. I want to remain a human. This human that *I* am, that is. Just give me the ability to see that colour... nothing more, nothing less. That is to say, *add* this ability to all my other abilities, which I already have; do not strip me of my other abilities, in the process.
