1. Food

There are only few things that human beings need in order to survive – shelter, water and food. 


Here’s a rough survival guide:
1. Humans cannot survive more than three hours exposed to extremely high or low temperatures.
2. Humans cannot survive more than 3 days without water.
3. Humans cannot survive more than three weeks without food. 


Thus, Food = Life.


But foodies do not just like food as a matter of survival, foodies have an ardent or refined interest in food - they want to learn everything about food and be culinary experts.
