Freerice was established a few years ago as a way of getting advertisers to feed people. It tests your vocabulary with a simple game - for every synonym you identify correctly the advertiser donates 10 grains of rice to the World Food Program. Not only does it exercise your brain, it also feeds the hungry! What could be better?
Whenever I go to the site I have always tried to donate 1,000 grains (i.e. get 100 answers correct), reasoning that 1,000 grains would make a meal for someone. However, I now read on Wikipedia that it takes 20,000 grains to feed one person for one day. So I'm donating a snack at best.
Anyway, what about the vocabulary-building element of Freerice? Is it better than a free lunch - is it a free lunch that also makes you smarter?
I'm going to test myself every day and see whether my best level goes up, as a test of this. Of course, it may be simply that I am able to memorise some of the words I have recently seen (i.e. if the Freerice program keeps repeating the same words). However, I'm going to give it a go.
Today's effort (best level for 1,000 grains total donated): 51/60.
