The human body should have a particular weight for a particular height i.e: the height and weight ratio must be in a specified proportion to each other. If the height and weight are in proper ratios to each other, then the bodily functions take place smoothly.
Parol refers to verbal expressions or words. Verbal evidence, such as the testimony of a witness at trial. In the context of contracts, deeds, wills, or other writings, parol evidence refers to extraneous evidence such as an oral agreement (a parol contract), or even a written agreement, that is not included in the relevant written document.
Once a contract is reduced to writing the courts say they will not hear any oral evidence If there is evidence in writing (such as a signed contract) the terms of the contract cannot be altered by evidence of oral (parol) agreements purporting to change, explain or contradict the written document.
