Expert writing Tips
Best practice
When describing changes associated with aging, be specific. Instead of just saying something changes "as they age", specify how it changes (e.g., "As they age, their skin loses elasticity").
Common error
Avoid using "as they age" as a blanket statement to explain all declines or changes. Not all effects are solely due to age; consider other factors like lifestyle, environment, and genetics.
