How do people get sick?

Answers

Answer:

Viruses spread through tiny droplets in the air that are released when a sick person sneezes, coughs, or blows their nose. You can get sick if you touch your nose, eyes, or mouth after you have touched something contaminated by the virus, such as a toy, countertop, or doorknob.

Explanation:

It also spreads by hand-to-hand contact with someone who has a cold or by sharing contaminated objects, such as eating utensils, towels, toys or telephones.

Brenna's mother recently fell down the lowest step of their front porch while scooping snow, and she cracked her ulna. Brenna gets angry at her mother for scooping the snow in the first place when she knows she has osteoporosis and a tendency for falling. Brett hires a snow removal service that will arrive as early as possible after future snows to prevent this from happening again, because they both know that Brenna's mom is going to continue to shovel. She still feels young, and she says her osteoporosis and age aren't holding her back in life.

Brenna and Brett both feel that even though Brenna's mother has a history of falling every couple of years, she is overall very healthy compared to others her age. Brett's mom on the other hand is only a few years older and very active in her local community organizations and tennis league.

Functional status is a better indicator of health in older adults than age, because how they have taken care of themselves over their lifetime greatly affects how they feel and function. Two different 70-year-olds can have completely different health statuses.

a. True
b. False

Answers

The statement 'two different 70-year-olds can have completely different health statuses' is TRUE. Health is a result of both environmental and genetic factors instead of only age.

Health is a physical and mental condition of well-being by which a person can develop his/her maximum potential.

The aging of a person is a process that occurs in an independent mode of different physiological pathways (e.g., maintenance, repair, defense).

In consequence, although aging is often associated with different diseases, aging in itself is not a disability/disease condition, thereby a person may have 70 years old and exhibit excellent physical/mental conditions.
