The average person can go about two weeks without food, and judging from some of the fat asses I saw on TV most of these people could go a month without starving.
I don't believe any of these people were starving after five days.
Not exactly demonstrating "starving Ethiopian" weight standards, are they?
I think there were old infirmed people who have died. Some from heat, some from dehydration.
I imagine there was enough food and water there, but if you didn't have the means to actively seek it, there probably wasn't anybody who was going to take care of you.
This reminds me of the 15,000 people who died of heat in France a couple of years ago.
