Physical Conditioning Skill

[JimmyPL56]

There should be a skill/trait related to physical condition (as well as mental) that can fluctuate based on your activity level. Some general thoughts on the details:

1. It is a skill similar to fire starting and mending that can raise or lower level in-game.

2. Every day the skill points are raised based on the amount of activity, or lowers/stays the same based on the amount of inactivity. The more walking, running, climbing, etc. you do the more it goes up.

3. Give the option to exercise while cooped up indoors (pushups, situps, etc.) to counteract inactivity and/or raise the skill/rate up. Can only do it in certain areas, and for a max amount per day. Of course it will lower your stamina/food/water bars based on how long you exercise, but temporarily increases temperature bar. Maybe additional benefit is it helps stave off cabin fever?

4. Once you raise up to level 2+ in Conditioning, then you can travel farther without getting tired and/or carry more weight without being encumbered.
