Expert writing Tips
Best practice
Consider using the preposition "with" instead of "in" (e.g., "progress with age") if you want to emphasize the simultaneous nature of the two developments.
Common error
Avoid using "progress in age" if you actually mean the biological deterioration of an organism; in that case, "senescence" or "biological aging" is more precise. "Progress in age" implies a neutral forward movement through time rather than a decline in health.

Ludwig's WRAP-UP
In summary, "progress in age" is a specialized phrase most frequently encountered in Scientific and Academic writing. Ludwig AI identifies it as a precise way to describe chronological advancement, particularly when analyzing data sets or biological trends. While it is perfectly correct from a grammatical standpoint, it is rarely used in casual conversation, where phrases like "getting older" or the "aging process" are preferred. Writers should choose "progress in age" when they need to maintain a neutral and objective tone regarding the passage of time and its effects on a subject. It is particularly effective in research contexts to denote the movement from one age bracket to the next.
