How to Save for Your Retirement in Your 50s

I’m writing a piece for Colonial Life on how to save for retirement in your 50s: -What should individuals do if they’ve put off saving for retirement and now in their 50s? Is it too late for them to start investing?
-Beyond investing, what are some other retirement planning areas someone in their 50s should focus on? How big of a role should life insurance play in that? -How should parents in their 50s balance retirement planning vs. helping a child in college if they’ve not begun saving for retirement? -What big expenses should those in their 50s focus on reducing? Is it ever advisable to take a mortgage payment into retirement? Requirements: Preferably someone from the financial services industry or financial advisor. If you’re from a PR firm, please have the quotes sent directly and not an offer to connect or have a call. Please send responses in quotable sentences as that would be most helpful. Please no product pitches.
