I know a couple of doctors and they don;t do 70 hours a week, the only ones that do do so out of choice due to the £300/hour overtime payments.
I don't know any nurses that work more than 12 hours a day for a sustained period.
Also drug trials have always taken then long to complete, are you really trying to say that's a recent development. It's to prevent a thalidomide from happening again.
It also takes that length of time to test the efficacy of the drugs in question. What's your alternative?!?! Some geezers get together and say 'hey let's mix that **** with that **** and it'll probably be good for something'?
Seriously, you say some weird things but complaining about the length of drug trials is probably the weirdest. That India produces clones is something that needs to be addressed (again, it doesn't happen nearly as much as you're trying to imply), but drug trials are the length they are for a very, very good reason.
Those that fail don't fail because of the fear of litigation, they fail because they discover the drugs don't work.
