I just learned about this through a friend-
There's a courageous and inspiring youtuber who just posted this challenge:
(btw, that is his real voice it is not an act)
You can earn rice for the UN to donate to the hungry people of the world by visiting
www.freerice.com
and building your vocabulary (sorry it's English only as far as I can tell).
Great way to spend some time improving the world and yourself.
Once you've earned some rice, if you're a youtuber, visit Ghostwise and let him know that his video inspired you, and how many grains you earned.
peace, j.
