What is the difference between life expectancies for someone who was born in 1900 and someone who was born in 2010?

Life expectancies for those born in 1900 were lower compared to those born in 2010. Advancements in medicine, technology, and living conditions have contributed to longer life expectancies over time. Someone born in 1900 had a life expectancy of around 49 years, while someone born in 2010 had a life expectancy of around 79 years.
