A study of people who were all chronologically 38 years old found their biological ages ranged from 28 to 48, a 20-year difference driven by early life experiences.

After centuries of linear increases, the human longevity curve began to slow and flatten around 2012, primarily due to growing socioeconomic disparities.

The saying 'you are as young as you feel' has scientific validity, as people who perceive themselves as younger are biologically fitter and cognitively sharper.

Understanding if you are a dolphin, lion, bear, or wolf chronotype can help you structure your day, as society is primarily built for lions and bears, putting wolves at a disadvantage.

Social isolation is biologically toxic, with animal studies showing it upregulates genes for inflammation and downregulates genes that protect our immune system.

Genes only contribute to 20% of the aging process, while the other 80% is within our control through lifestyle and environment.

Contrary to the idea of slowing down, the advice for people over 50 is to do a little bit more each year in terms of exercise, dietary variety, and creativity.

The Roseto study showed that a town of immigrants with a poor diet had exceptional longevity, which was attributed to their incredibly strong social and community bonds.

A recent study showed that simple lifestyle changes in diet, exercise, stress, and sleep reversed participants' biological age by over three years in just eight weeks.

Research shows that quality of life consistently improves from age 50 and doesn't return to that baseline level until age 84, unless impacted by physical illness.
