Can you live on just $1.50 worth of food and drink for five days?

You could test yourself, while helping to bring awareness to world poverty, as part of the Live Below the Line anti-poverty campaign.

Ben Affleck has signed on, tweeting, “1.4 billion people live on less than $1.50/day. I’m joining Live #BelowTheLine on behalf of @easterncongo. Will you?"

The campaign runs from April 29-May 3. Actress Sophia Bush and singer Josh Groban have also reportedly signed on, and Hugh Jackman is featured in a video on the official site, explaining more about the campaign.
