Is $6 million enough to retire at 65?

I'm curious, is $6 million truly sufficient to retire comfortably at the age of 65? With the ever-fluctuating nature of the market and the potential for inflation to erode the value of savings over time, is this amount really enough to sustain a comfortable lifestyle in retirement? Or should one aim for a higher nest egg to ensure financial security in their golden years? It's a question that many soon-to-be retirees grapple with, and I'd love to hear your thoughts on the matter.
