Food for the hungry

I am a crossword puzzle addict, an activity that many people close to me consider a not very constructive use of my time. Really? Well, I’m using my vocabulary to feed the world’s hungry.
I just learned about a website called www.freerice.com, where I can turn the formerly useless vocabulary I have picked up from doing crosswords into rice that is donated to the hungry around the world. You can too, no matter what level your vocabulary is.
Just log onto the website and start taking the vocabulary quiz that you’ll find there. For every word you get right (it’s multiple choice), 10 grains of rice are donated to We Feed People, an international humanitarian agency that gives food to 90 million poor people annually. The quiz automatically adjusts to your vocabulary level. So it’s a useful learning tool for new words whether you’re just learning English or you want to try to get to the highest level. I’m planning to learn new obscure words for the Friday New York Times puzzle.
The site is underwritten by advertisers, whose space on the site is actually quite unobtrusive. One billion grains of race have been donated in the first month the site was up.
