... so, from statistical point of view - xe/ze is actually a he. xe/ze has huge overlap with he, but very limited overlap with she, while at the same time there is a large amount of "she-only" flicks.

... I am asking, because in my european (post-communist) country, the numbers would be 47 -> 60. I always thought, that this was quite wild, considering that during communism our state encouraged women to study, and during this time we had +/- parity, but the number got much higher afterwards. Do you know what was the reason for the abnormally high numbers of female graduates in canada already in 1992?

... I would like to see in the graph also how the overall composition of all graduates from all fields have shifted - this would provide something to compare these numbers to...

... what is interesting as well is the colour of the mucus produced when you have cold. Especially during sinus infection, large amount of green snot is produced. But the mucus should be colourless, so where does this come from? The answer is, that it contains dead white blood cells - a result of a fight your immune system is waging against the infection. The colour itself is caused by haem (the same chemical, which carries iron and binds oxygen in haemoglobin). As a quite conjungated aromatic system, haem derivatives are often deeply coloured. What is really cool, is that the haem in the snot is mostly contained in an enzyme, which produces hypochlorite ions by oxidation of chloride (haem is usually contained in redox-active enzymes). So your body produces its own "bleach" (active agens in bleach is the hypochlorite) to disinfect your innards :)

... not really. Only slightly above 50 percent of world countries recognize kosovar independence. Not even all of the eu countries recognize it...

Yes, certainly. Drinking a bit, but regularly is much less damaging than getting completely shitfaced once/twice a week. If you compare e.g. spain, france vs. poland, estonia, you again see more-or-less the same average in alcohol consumption. On the other hand, deaths from alcohol-related diseases are 0.6; 3.8; 8.2; 12.2 (!!) per 100k, respectively. Binge drinking damages health WAY more than regular modest drinking.

... per capita average is not telling the whole story. Important part is also HOW this average is achieved - norway and greece have the same average, but greeks have a cup of retzina for lunch and then an ouzo digestive in the evening, and maybe a coffee with cognac in the morning - and do this every day. In norway, people are not drinking at all during the weekdays, only to get completely shitfaced on friday night...
