Temp Metabolism and Temperature

Ideas and sketches for Metabolism, Temperature Tolerance, and perhaps Sleep as well. Maybe also Tan (Sun Resistance) eventually.

The Human norm is 6 Levels of Temperature Tolerance, distributed as desired between Cold Tolerance and Heat Tolerance, but with zero Levels as the minimum for either. This amount of 6 Levels can be sold down or bought up.

The "true Human norm" is 3 Levels vs Cold and 3 vs Heat, which is for Human racially adapted to a Mediterranean climate. Someone living in Denmark or Northern Germany would have 2 vs Heat and 4 vs Cold, while a Norwegian might have 1 vs Heat and 5 vs Cold, and an Inuit (Eskimo) have 0 vs Heat and 6 vs Cold.

The "gains" are such that players are strongly discouraged from very uneven distribution of the Levels. It is therefore assumed that when very uneven distribution occors, it is because the player thinks it is "true to the character's concept".

A total of 2 or 3 levels of Temperature Tolerance is highly unusual, and is usually only found in very weakened people. Perhaps some people undergoing chemotherapy? It can also be argued that Human variety should be limited to a maximum of 8 or 9 Levels of Temperature Tolerance, but the 10th is included just 'coz.

All temperatures are in degress celsius.

The threshold values are such that at th first value, penalties for being too warm kick in. Once the second value is reached, more severe penalties take effect, and if the third value is exceeded, extreme penalties take effect. An example is that after the first value, for heat water requirements are increased while for cold the required daily intake of food is increased slightly. After the second value, for heat the water requirement is increased drastically while for cold the food requirement is increased markedly. And so forth.

Metabolism

Diet

Humans are defined as Omnivores, meaning they can survive on both animal and vegetable food, unlike herbivores and carnivores.

In deeper detail, Humans should be defined as Omni(V), the "V" standing for vulnerable, meaning that they must have a varied diet as the are unable to produce many proteins and vitamins that other animals can create internally. A cow can survive just fine on grass, for instance, making its own vitamins and all necessary amino acids. Since Humans are the assumed norm, however, it may be more reasonable to have "V" be the assumption, and to denote the deviation from this norm as "Omni(R)", the "R" standing for robust. The implicit assumed norms for Herbivores and Carnivores, in terms of whether it should be V or R, is as yet undetermined.

Metabolism stat

The Metabolism stat is used to derive the daily requirement of food (in Energy Units), water (H2O) and oxygen, with the later usually being ignorable in most campaign types.

For Humans, a simple linear formula is used to convert a given Metabolism value to EU or water needs, or oxygen needs. The exactly conversion for food has not yet been determined, but a Metabolism of 3 means 3 Energy Units. It is the precise value of 1 EU that is not yet decided, but a tentative value is 750 kcal, although expressing it in joules would be neater, and more in keeping with Sagatafl's tradition of being pro-science.

For water it is 0.5 kg (0.5 liters) per Day, and for oxygen it is 0.3 kg/Day (and note that this last fiure is a simplification for game puposes, distilled selectively out of several conflicting sources, in a not-very-thorough manner. Do not use it for any real life activities or experiments!)

One minor issue is whether Metabolism should convert linearly into values, or use the Temp Attributes and Non-Linear Effects system where higher values yield slightly higher results. Well, actually for very low Metabolism values, NLE must be used, so it's simpler just to use it everywhere.
