How a Secure Retirement Portfolio Can Extend Your Lifespan
Financial security in retirement may do more than protect your savings — research suggests it can literally add years to your life.

This reframing matters for how financial advisers communicate with clients nearing or entering retirement. The conversation is typically anchored in numbers — rates of return, tax efficiency, sequence-of-returns risk.
