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