Fit as a fiddle
Die
Right as rain
To be okay after an illness
Have a sore throat
Kick the bucket
Under the weather
undergo a surgery
Describe someone who has trouble seeing
Under the knife
A frog in your throat
To be in very good health, especially connected to elderly people
Not feeling well
A brush with death
Almost die
be almost dying
Blind as a bat
One foot in the grave
Die
Pushing up the daisies
