Aneli [31]

Correct answer choice is:


A. Family meals.


Explanation:


Few chronic diseases are entirely recognized as “conditions” of extinction. Cardiovascular disorder, various cancers, stroke, and incurable lung disorder are the most frequent conditions of death. There are several other long-standing disabilities, though, that may or may not immediately cause death but may have many consequences on a state of life. Chronic diseases frequently create annoying health difficulties for those harmed and/or those nearby them, difficulties that continue over time. These involve difficulties with physical fitness, mental strength, or social well-being, all of which are linked with inferior quality of life. In many people with incurable diseases, a moderate impairment in any particular one of these features of fitness points to impairments in other features and may proceed moreover to disability.
