The death penalty and nutrition

[MagpieOAO 18]

Nutrition should affect quality of stats, vulnerability to disease. Disease, malnutrition and death should decrease it.

You should be able to survive on any given type of food but to be healthy you will need nutrition. Without nutrition you will start to receive penalties on your stats including after a revive at which point you start at a reduced nutrition level. Nutrition should be readily available at traders in free ports so you always have some method to obtain nutrition (Likely fruits, which won't last long on the seas) at a cost and some risk. 

This runs the risk of a death cycle, but given at rock bottom you should spawn at a free port, you should still be able to scrape some things together to sell for fruit to regain your nutrition.
