Final answer:
The rise in life expectancy can be attributed to improvements in healthcare, emphasis on healthy lifestyles, and advancements in public health measures.
Step-by-step explanation:
The rise in life expectancy can be attributed to several factors. Firstly, improvements in healthcare have played a significant role. Access to better healthcare and advancements in medicine have allowed people to live longer. Additionally, there has been a greater emphasis on living a healthy lifestyle, with increased awareness of the health risks associated with behaviors such as smoking, excessive alcohol consumption, and drug use.
Lastly, advancements in public health measures, such as clean water systems and sanitation, have also contributed to longer life expectancies.
This longevity is due to better health care and hygiene, healthier lifestyles, diet, and improved medical care. We have access to antibiotics and vaccines, clean water, plentiful and more nutritious food, and we know that exercise and smart lifestyle choices improve our quantity and quality of life.
However, while most people imagine medical advancements to be the reason for this increase, the largest gain in life expectancy occurred between 1880 and 1920 due to public health improvements such as control of infectious diseases, more abundant and safer foods, cleaner water, and other nonmedical social improvements.
