On average Niger women have 7 children and presumably raise them on 2*GDP per capita income.
AFAIK, “per capita” means ‘divided by the whole population’, not just the adult one. (Am I missing something?)
Aside: how do you make links here that include parentheses in them?
[Like this](http://en.wikipedia.org/wiki/List_of_countries_by_GDP_%28PPP%29_per_capita) (28 and 29 being the ASCII values for ( and ) respectively in hexadecimal).
Good point and thanks for the tip.
Thus spake Eliezer:
It seems that many here might have outlandish ideas for ways of improving our lives. For instance, a recent post advocated installing really bright lights as a way to boost alertness and productivity. We should not adopt such hacks into our dogma until we're pretty sure they work; however, one way of knowing whether a crazy idea works is to try implementing it, and you may have more ideas than you're planning to implement.
So: please post all such lifehack ideas! Even if you haven't tried them, even if they seem unlikely to work. Post them separately, unless some other way would be more appropriate. If you've tried some idea and it hasn't worked, it would be useful to post that too.
