Question

Quizplus · Accepted Answer

Advances in medicine have contributed to the majority of the increase in life expectancy of people aged 65 years and older. Medical treatments have improved, leading to better management of chronic illnesses, and the development of new drugs and procedures have allowed for a longer and healthier life for many seniors. While improved housing, safe water, and lower levels of stress also play a role in overall health, they do not account for as significant a portion of the increase as advances in medicine. Conversely, diet can be an important factor in health outcomes, but it is only one among many and has not been the driving force behind the increase in life expectancy among seniors.
