Question

a person can stay positive through aging if they _____.
keep their mind youthful
say their goodbyes early
give their stuff away as they want

Explanation:

To stay positive during aging, mental approaches matter. "Keep their mind youthful" aligns with psychological concepts of maintaining a positive, active mindset (relevant to Psychology, a Social Science subfield). The other options (saying goodbyes early, giving stuff away) are less directly tied to positive aging psychology.
