The old man suddenly keeled over while walking
She felt dizzy and nearly keeled over
The plant had not been watered and keeled over
He was so tired he almost keeled over
The sudden news made him keel over
The exhausted runner keeled over just before the finish line
If you don't eat, you'll keel over
The heavy heat caused me to keel over
The horse keeled over from exhaustion
I felt faint and thought I would keel over
I feel so dizzy, I might keel over.
Sit down quickly, you look pale.
I just need a moment to recover.
The old sailor would sometimes keel over from exhaustion
The tired sailor sometimes collapsed from exhaustion
The weary sailor often fainted from fatigue
