If you're bored, or simply want to help others in the world, go to these two websites and play the games. Freerice donates 10 grains of rice to the World Food Programme, for every correct answer you get while playing a vocabulary game. It is entirely free to play.
Freekibble is pretty much the same thing. You answer questions, and they donate dry kibble to animal shelters all over the world. There is also a link to play to win kibble for cats also.
