Depending on the type of loan, and when it was taken, the interest rates on student loans very greatly. If you have some that were low interest due to timing or subsidizing (0% interest in some cases), it can make sense to pay the loans slowly and invest or save money instead. So the age of the loans isn't a reliable predictor of their burden.
