Your sentence is clear but can be made more natural. Here are two corrections and some tips:
1. "Yes, but he is too old to come back again."
Correction: "Yes, but he’s too old to come back."
2. Alternatively: "Yes, but he’s too old to return now."
Tips:
- "Come back" and "return" are similar; "return" sounds a bit more formal.
- "Again" is often unnecessary if the context already implies repetition.
- Using contractions ("he’s" instead of "he is") makes speech sound more natural and conversational.
