Hm, admittedly, I know next to nothing about this, but is it possible that there was no single cause for the extinction event? Maybe it was both the asteroids and the volcanoes - or asteroids and an unusually long period of drought that destabilized the ecology enough to "prime" the situation for a mass extinction?
I learned something new today - thanks PlasmaGryphon! I thought that CMOS is low cost but low-quality and low-resolution but apparently, they're practically on par with CCDs nowadays.
Interesting, rcxb! I think you're definitely right that we are often tempted to attribute a single cause to a complex problem like obesity (i.e. lots of food leads to fat people).
And it's also interesting that we naturally assume that Americans are the fattest people in the world. In fact, Mexico has surpassed the USA in this term - and processed food seems to be a leading factor (even in rural areas).
Where abroad did you find that food portions in restaurants are larger than in the USA, Edward? My experience is the opposite: food portions in the USA is far larger.
And lying down on the oily lanes is also bad form!
