Hallmarks and cellular changes described
According to the description, the episode explores why aging begins long before visible signs appear. It names key drivers, called hallmarks, including mitochondrial dysfunction, stem cell exhaustion and declining communication between cells. The description says these changes can affect energy, inflammation and the body's ability to repair itself. It also lists questions the hosts tackle, such as when biological aging begins and why identical twins can age at different rates. These are topics the description says are discussed; the video and transcript were not reviewed.
