Each storage cell can store a fixed amount of data. Each type consumes a number of bytes (which varies with the cell size), and each item consumes one bit of storage, so eight items consume one byte, and a full stack of 64 consumes 8 bytes, regardless of how the item would stack outside an ME network. For instance, 64 identical saddles don''t ...

Between meals, stored fat is slowly released, keeping our cells supplied with fuel. While the brain needs glucose, our liver, muscle, and fat cells prefer to burn fat. When calorie consumption is in balance, we maintain a healthy supply of fat that''s available when we need it. This extra energy reserve helps us survive longer periods of fasting ...
