Don't think you could eat on $1 a day?
This man was able to spend less than $30 on food for an entire month.
One of the few spots we splurge on is going out to eat (I don't see you driving a '92 Pontiac Sunbird with the cassette deck (which actually comes in handy for easy hookup to my Zune. Yes, I said Zune...not i-pod)). But, this is certainly thought provoking in many ways considering $1 may be equal to many people's hourly/daily wage around the world.
Maybe my extra frugal sister will take up this challenge?
On a similar note, if you've never checked out Global Rich List to see just how fortunate you are then I suggest you do. All you need to know is your annual income.
