Not only can these activities cause pain and discomfort, but these physical positions can limit other job activities such as lifting, pushing, or pulling weights without substantial body stress. [16] Potential solutions for common ergonomic hazards include: [16] raising the work off the floor and onto a worksurface closer to the worker;
A cartoon character producing an object from nowhere - from "hammerspace" Hammerspace (also known as malletspace) is an imaginary extradimensional, instantly accessible storage area in fiction, which is used to explain how characters from animation, comics, and video games can produce objects out of thin air.

Grip strength is the force applied by the hand to pull on or suspend from objects and is a specific part of hand strength. Optimum-sized objects permit the hand to wrap around a cylindrical shape with a diameter from one to three inches. Stair rails are an example of where shape and diameter are critical for proper grip in case of a fall.

This exercise can also be called a triceps push-down or a two-armed standing triceps extension. The exercise is completed by pushing an object downward against resistance.
For this reason, more pictures are drawn near the beginning and end of an action, creating a slow in and slow out effect in order to achieve more realistic movements. This concept emphasizes the object's extreme poses. Inversely, fewer pictures are drawn within the middle of the animation to emphasize faster action. [12]
