As somebody who presently lives 3 blocks from this, let me tell you, this "art" project is TACKY. It would work in Las Vegas, but the Bay Bridge is too dignified for this sort of crap. Can't wait for it to be removed.
Read the next line: "Compared to abstainers, those who drank 3 cups of caffeinated coffee daily were at increased risk of EG/EGS (RR = 1.66; 95% CI, 1.09–2.54; P trend = 0.02)."
Still, given that there were 120,000 data points in this study, and they don't seem to be correcting for multiple comparisons, I would think a P of 0.02 is pretty weak.
And while the 3G may be listed as supported on iOS 4.2.1, it's so slow running this OS that realistically it's not supported...
