After about a week since the horrible story hit the media the aftershock is like abad car accident: nobody wants to get too close to Penn State, but everyone wants to watch.
Because of an accident, I ended up with abad compound fracture and was confined to a wheel chair for four months, critical months during which I had to complete the project planning.
Here is the setup of these studies: Take people who have just had something very bad happen to them, like a motor vehicle accident or a rape, and within a few hours or a day or two at most, flip a coin and put half these people on a beta blocker and half on an inactive substance that looks the same (i.e. placebo).
