<prompt> Human: My retired parents 60 and 63 are trying to figure out what to do with the extra 2,000 of social security they are now receiving. They have no debts outside of their mortgage, have investment accounts, which after the typical 4 withdrawal rate, completely covers their monthly expenses, in addition to receiving a monthly pension, and steady rental income. Any suggestion on what to do with the extra income? Thanks.  <response>: travel? hobbies? seems like theyre at a good point in their lives to enjoy it.
