What is the first part of your body to age? An in-depth look
According to a 2025 study from the Max Planck Institute for Biology of Ageing, certain bodily systems can begin to decline as early as your twenties, with the aorta showing signs of age before many other organs. While many people focus on wrinkles on the face, the question of "What is the first part of your body to age?" reveals a more complex answer involving both visible changes and hidden internal processes. The true answer depends on whether you're looking for the first noticeable external signs or the earliest internal changes at a cellular level.
