Aging biology topics listed in the description
The description says the episode explores why aging is a complex biological process and reviews drivers such as DNA damage, telomere shortening, mitochondrial dysfunction, increased inflammation, senescent cells and epigenetic changes shaped by environmental exposures. These are described as areas reviewed in the episode; the description gives no study details, measurements or results for them.

NAD, calorie restriction and fasting in the description
The description names NAD supplements and calorie restriction or intermittent fasting as emerging areas of interest. It mentions evidence from animal research that reduced calorie intake can improve biological aging markers. It also says fasting is not for everyone and may not be ideal for some women. The description does not report human lifespan or health outcomes for these approaches.
