The chosen valedictorian is often the student with the highest ranking among his/her graduating class. The term is an Anglicised derivation of the Latin vale dicere (to say farewell), historically rooted in the valedictorian's traditional role as the final speaker at the graduation ceremony.
The human body cannot survive without food and water for long periods of time. In fact, according to SurvivalTopics.com, the longest a person can go without water is 10 days--without food, it's four to six weeks.
How Many Days You Can Go Without Food (but With Water)? A malnourished person without much body fat and muscles can die after not eating for few days. On the other hand, some people are able to fast (not eat deliberately and only drink water) for 40 days. Factors influencing length of survival without food: 1  Starting body weight: physiologists agree nobody can survive losing 40% of his initial weight. 2  Initial amount of fat. When body does not get any food, it starts to use glycogen stores from the liver, which suffice for 1-2 days. 3  Initial amount of muscles.
