And then, as part of the same PA about dimming of lights, SLF are told that they can use the reading light if they wish...
...and continue to do so because the number of actual evacuations is so very small that natural selection never has a chance to kick-in.
Although I understand that the sort of time frame we're talking about here is generally not enough for one's eyes to actually dark-adapt, I, for one, will accept any tools offered when it comes to getting my carcass out of the airframe alive.
I'd like to see a study which correlated individuals who turn on their reading light when the lights dim with those who stand up and pull their 50 pound bags out of the overhead during moderate or better turbulence, and those who take their seat belts off during taxi-in. Grrrrrr.

PS The new spell-check is really delightful. Thanks Danny!
