Are we really living longer than 100 years ago?

I would think it depended upon where you live at. There are some countries that are doing worse now than before due to AIDS and other new diseases that inflict heavy death rates there. Then overpopulated countries are seeing a lowered amount of time to live. So , like I think, depends upon where you live is if your living any longer.

a 2007 paper studying this question. Quote:

"The modal age of mortality in hunter-gatherers can range from 68 in the Hiwi to 78 in the Tsimane. In the united states as of 2002 the mode age of mortality was 85. In most cases about 30% of of adult deaths occur at ages above the modal age of mortality."

So apparently it isn't just 100 years ago, but 1000s of years ago.

"We hypothesize that human bodies are designed to function well for about seven decades in the environment in which our species evolved. Mortality rates differ among populations and among periods, especially in risks of violent death. However, those differences are small in a comparative cross-species perspective, and the similarity in mortality profiles
of traditional peoples living in varying environments is impressive."

It appears that our younger compatriots have skewed the mortality data.
