Does anyone else but me think that pharmaceuticals are holding back with cures for anything?

If you think about how much money is dumped into Cancer / Aids research each year why haven't they come up with anything yet?

If you think how much a billion dollars is and how many salaries it could pay for a year I think any country within a year could find a cure... that's why I think with any cures for any health problems there are some being held back.

They get money from the goverment / charities and then they also charge incredible amounts of money for the drugs ( saying they have to pay for the R&D) I don't know but to me that's really sketchy.

I'm a researcher who has to track, retrieve, and make use of a large number of journal articles, books, newpaper clippings and websites.  These items are both hard copy and electrinic.

I'm looking what type(s) of systems can be used to build a robust library.  I've got Endnote on the way but am still thinking about the physical (and virtual) organization of the materials.  Any suggestions?

"Such and such reduces the chance of heart disease by 80%."  "This and that increase the chance of heart disease by 25%."  We hear these statistics so often they've become meaningless, so I'd like to know...what is the chance of heart disease?  One in 10,000?  One in three?  (One in three Americans die of heart disease, so is that what they're referencing?  Is it like charting the chance of death, despite knowing that everyone is going to die?)
