I have always been wondering how people get paper cutsI know that the paper cuts them in some way, but i want to know how paper cuts human skinIf it is possible, i would like a long explanation explaining like how, why, etcThank you.
A paper cut occurs when a piece of paper or other thin, sharp material slices a person's skinPaper cuts, though named from paper, can also be caused by other thin, stiff materials, such as aluminium foil, thin blades of grass, or film negativesAlthough a loose paper sheet is usually too soft to cut, it can be very thin (sometimes as thin as a razor edge), being then able to exert high levels of pressure, enough to cut the skinPaper cuts are most often caused by paper sheets that are strongly fastened together (such as brand new paper out of a ream), because one single paper sheet might be dislocated from the restThus all the other sheets are holding this dislocated sheet in position, and the very small part held away from the rest can be stiff enough to act as a razorPaper cuts can cause surprisingly acute pain since they usually stimulate a large number of skin surface pain receptors (nociceptors) in a very small area of the skinBecause the shallow cut does not bleed very much, the pain receptors are left open to the air, ensuring continued painThis is exacerbated by irritation caused by the fibers in the paper itself, which may be coated in chemicals such as bleachAdditionally, most paper cuts occur in the fingers, which have a greater concentration of sensory receptors than the rest of the bodyThe random orientation of collagen fibers in skin provides the ability to withstand pinpoint forcesHowever, skin does not have the same strength against shearing forces, and is easily cutThe same principle can be applied to performers that stand on blades.
Fiber supplements are totally unnecessary as you can get ample fiber from fruit and vegetables where most of your fiber comes fromThere is also fiber in grains and cereals but a lot more in fruit and vegetables.
