Two systems named in the description
According to the description, the video identifies two processes in the body that speed up around age 75. It names muscle strength loss (sarcopenia) and immune system aging (immunosenescence and inflammaging) and says it covers how these two systems interact. The description also says falls and fatigue often appear together, but it gives no numbers or mechanisms. [1]
Resistance training evidence claimed for 75+
