It looks like your sentence got cut off at “old men have the…”. To give an accurate answer, I need the full statement.
Common completions people mention include:
- “old men have the highest risk of certain diseases”
- “old men have the slowest metabolism”
- “old men have the best memory for certain things”
- “old men have the strongest sense of humor”
Could you clarify what you meant so I can give the full explanation?
