50 and trying to decide whether 60/40 is boring wisdom or fear in khakis

Age 50, retirement maybe at 63 if markets and knees cooperate. Risk tolerance medium. ive spent years around 75/15/10 and now im wondering if moving toward a classic 60/40 style mix is sensible or just me aging into caution.

Current allocation:
- 72% equities
- 18% bonds
- 10% cash

I know labels dont matter as much as behavior, but still curious how people in there 50s think about the old balanced formulas now
