This class explores aging as a multidimensional process through the lens of modern science and traditional medicine. We will review key mechanisms such as genomic instability, oxidative stress, inflammation, and hormonal decline, alongside traditional frameworks from Ayurveda, Traditional Chinese Medicine (TCM), and Physiomedicalism. Emphasis will be placed on classical rejuvenative approaches adapted to the modern age, including rasāyana (Ayurveda), yǎng shēng (TCM), and trophorestoration (Physiomedicalism), with discussion of relevant materia medica. Selected pathologies and their treatment, associated with menopause and andropause, will be examined from both a biomedical and traditional perspective.
