You probably enjoy a better life than John D. Rockefeller did 100 years ago. Rockefeller lived in a big draughty house with lots of servants. Cars were primitive as was medicine. No refrigerators, washing machines or other domestic appliances we take for granted. Running water, much less safe tap water were brand new inventions at best. He lived a long life. The odds of getting to the age of 15 when he was born were probably better than 50%.
People forget how horrible the good old days before the Industrial Revolution really were.
The great increase in life expectancy of all classes of people should never be underrated.
