Most surgeons recommend not eating or drinking most fluids for eight to 12 hours prior to surgery. You can usually drink clear liquids like water, apple juice, or chicken broth, but should stop drinking anything four hours beforehand.
An object reference is required for the nonstatic field, method, or property 'member'. In order to use a non-static field, method, or property, you must first create an object instance. For more information about static methods, see Static Classes and Static Class Members (C# Programming Guide) . For more information about creating instances of classes, see Instance Constructors (C# Programming Guide) .
Likewise, an inertial frame of reference is a reference frame in which an object stays either at rest or at a constant velocity unless another force acts upon it. When a body does not seem to be acting in accordance with inertia, it is in a non-inertial frame of reference or accelerating. Newton's Law & Frames of Reference
