ahh! It's a time-suck. So addictive. But they don't tell what the relative levels mean (where am I between a two year old and mensa? I want to know)! And is it cheating that words can repeat when the site restarts the quiz process, so I automatically get them right?
I will have to visit the kitchen and count rice grains to see how many cups worth (meals!) have been donated by me so far... (more time lost to the cause, ah well)
