When a character has a lot of objects and a lot of weight - the character has a small supply of energy, below 10%, he can run, jump, restore energy and run again. But the character cannot hold his breath when aiming through the scope at the target. The problem arises if once fatigue reduces the margin of strength to 0%. After that, the character can run, but the breath holding will not return. The character can return the breath holding if, for example, throw a backpack on the floor. The force scale will be restored to a value above 25-30%, the character will again be able to hold his breath and pick up a backpack, run and jump. As soon as the "reserve of forces" stops at 0% - "Holding the breath" will be blocked.
