Refinance My Mortgage

Is it better to Refinance A Mortgage for a tax deduction or continue with my 15 year mortgage?
I have 10 1/2 years left on a 15. Single, retired and no dependents.Pension(60,000) Does it make sense to refinance?
Interest rates dropped to around 6.10% for a 30 year loan. What is your interest rate. Will you save money by refinancing? Your mortgage does not account for much of a deduction. You may want to stay the course.
