I model the decrease in human lifespans after the Flood due to a combination of factors beginning at the Curse, including divine sustainment, loss of physiological resilience and changes in Earth's environment. Current research indicates a hard limit on human lifespan due to physiological resilience limitations.

In this presentation I discuss the drastic reduction in human lifespans after the global flood, from 910-970 years to about 70 years. I link these changes to factors such as biological decay, genetic entropy, Earth’s altered magnetic field and loss of physiological resilience. Eternal lifespans can only be restored through Jesus Christ.
