5 Must-know English Idioms About Health to Exercise Your Language Skills

Like all English idioms, health idioms are a common part of daily
speech and conversation. Let’s see the following common idioms and
practice them in your daily life.
1. Alive and kicking
The idiom means something that’s (still) functioning in a good way.
This can be a person, an object, or even an idea! The reason I wrote still in
brackets is that alive and kicking often refers to something that’s perhaps old
or thought to be useless.
“Do you still have that motorbike you bought in the 1970s?”
“Yeah, and it’s still alive and kicking.”
Look at another example:
“My grandmother is still alive and kicking at 89 years old. She never
slows down!”
2. As fit as a fiddle
To be as fit as a fiddle is to be in excellent physical shape or to be very
healthy.
For example:
“Are you ready for our run this morning?”
“Ready?! I’m feeling as fit as a fiddle.”
3. Under the knife
This idiom sounds a little scary, and, in some cases, it can be. To go under
the knife is to have surgery or an operation.
Because of the use of the word knife, the idiom usually implies (suggests) that
it’s serious surgery.
Let’s see the following example:
“How’s your brother?”
“He’s ok; he’s going under the knife next week to have surgery on
his stomach.”
4. A clean bill of health
A clean bill of health is when a medical professional acknowledges that
you’re healthy and free from health-related issues. Let’s see the following
example
“The local biologist assessed the river and found it to be healthy. He gave
it a clean bill of health.”
Here’s a second example:
“The hikers who were lost in the woods for two days received a clean bill of
health from the local physician.”
5. A picture of health

This idiom means to be in great physical condition. Usually, it refers to
somebody who’s in visually great condition. We often use the determiner “the”
when using this idiom to describe an individual. For example:
“Have you met my Uncle Paul?
He drinks every day, but he’s still the picture of health!”
