It costs you money for your HCBW to retire before you do.
Before my HCBW's retirement, we both worked long days, and rarely traveled more than once a year besides for work.
Now, the HCBW, whose mind was always moving while working, is still moving at the same pace. Yet, she needs to find things to do, and those things to do include shopping and finding travel deals, delaying Archaea's eventual or possible retirement.
Retire before your HCBW, guys.
