SCIENCE, TECHNOLOGY, AND SOCIETY The aging process isthought to be initiated at the cellular level. Among the changesthat can occur after a certain number of cell divisions is theloss of a cell’s ability to respond to growth factors and other signals. Much research into aging is aimed at understanding suchlosses, with the ultimate goal of extending the human life span.Not everyone, however, agrees that this is a desirable goal. If lifeexpectancy were greatly increased, discuss what might be thesocial and ecological consequences.

Stress

Stress is defined as the feeling of being overwhelmed or unable to cope with emotional or mental pressure. Any event or action that makes a person annoyed, furious, or nervous can trigger it. Chemical changes in the body caused by stress can cause blood pressure, blood sugar levels, and heart rate to rise.
