Hollywood A lister Ben Affleck is going to live on $1.50 a day for "Live Below The Line", a part of the Global Poverty Project. Live Below The Line is challenging people to spend five days feeding themselves with only $1.50 a day, which is the U.S. equivalent of the extreme poverty line.

Celebrities Josh Groban, Sophia Bush, Debi Mazar and Hunter Biden. They've all pledged to go at least one full day. No official word if anyone is going to attempt to go the full 5 days.

The project is scheduled to run April 29 through May 3 -- do you think you could do it?
