Explain the effects that high and low self esteem have on health.

Answers

Answer:

If you have low self esteem it has a negative effect on health. They are more likely than their peers to use drugs, drop out of school, become pregnant, and suffer from eating disorders.

They develop a healthy balance of liking who they are, but also recognizing that there are ways they can continue to grow and to develop.

Why must prescriptions be written in ink?

Answers

Answer:

Medicine prescriptions must be written in ink because doctors (or whoever has prescribed the medicine) can not always trust that a patient will not erase the pencil and rewrite the prescription as something else like an addicting drug. Some patients are not to be trusted and that could get the doctor (or medical professional) to get into a lot of legal trouble. Pen prevents this from happening and also looks much more formal on a document of pharmaceutical slip.

prevention is better than care. give reason​

Answers

Answer:

When a disease affects the body, there will be a problem with the functioning of body organs. Medications will have to be administered and they could cause allergies as side effects. Also, there are some diseases for which the cure is not available. Therefore, prevention is better than cure because: Viral diseases and sexually transmitted diseases are hard to cure and once contacted, they can be life-threatening. Children have a weak immune system, they need to be immunized. Vector-borne, water-borne, air-borne diseases develop in the surroundings, so cleanliness should be a priority.

Answer:

Prevention is better than care, as prevention allows for the sustainability of the natural body, while care may alleviate the pain and problems in that arises, but would not return the objective to fully functioning, and if it does, there may either be foreign entities that, while it carries more positives then negatives, may not be as good as the original entity. Preventing allows for 100% functionality, while care allows it to function to the best of it's ability (but does not gaurantee a 100% functionality in the future).
