had one's wits about one

Remained mentally sharp

To have one's wits about one is to remain alert, clearheaded, and able to think quickly—especially under pressure or in confusing circumstances.

The phrase often appears in past tense to describe someone who stayed sharp when it mattered: She had her wits about her and grabbed the fire extinguisher before the flames spread.

The negative suggests confusion or panic: I didn't have my wits about me after the accident.
