I'm not vague, I'm just anaemic. Stark article in the New Scientist about the effects of low iron levels on cognitive performance. Apparently, if you drop below 120 grams/litre haemoglobin in your blood, your ability to remember things is slowed. And in this study it indicated slowed in half.
Which makes me wonder why menstruating is such an evolutionary plus.
I mean there has obviously been a massive evolutionary benefit for being smart, based on how smart we've got in such a short period of time. And yet, menstruating makes you stupid. So it must convey some critical benefit - which I'm quite, quite sure I can't see.
