All of these choices contribute to the observation that tissues heal faster and leave less obvious scars in the young compared to the aged. Younger individuals often have a better nutritional state, which supports efficient healing processes. Aged tissues tend to have a worse blood supply, which can slow down healing and contribute to more noticeable scarring. Additionally, cells in younger individuals typically have a higher metabolic rate, which can speed up the healing process.
