I'm with Hagar on this.
I can't see how my computer can possibly be used to help find a cure for cancer?
What information can they send me to have my computer process that can help find a cure? And if it is information that may help cure cancer why trust me with it?
All seems a bit strange, this has come up before about different things such as this, and finding ETs and since my computer can't cure its own viruses it sure the hell ain't going to cure any "real" illnesses.
Something like this is just to fishy if you ask me.
Think about it all the money available from Governments and charities, private lenders. they don't need to use private computers to work on "cures", find ETs, etc..
Hell they can make a portable phone that takes photos and connects to the internet, why not cures for common illnesses?
My opinion is the fact that such cures do already exsist, but would not be profitable to the Medical Community if they were used, that is why we see no cures

No sick people, no need for a Doctor

ps: Ozzy sorry to hear about your loss, I too have had it affect my life in a similar manner.
