“The average life expectancy there is something crazy like 82 years.”
You read an article about a small island where people live a long time. You're describing this place to a coworker who didn't read the article.
The average life expectancy there is something crazy like 82 years.
The "average life expectancy" is the average age that people live until. You can find out the "average life expectancy" for a country or region, or an overall average life expectancy for the world:
The average life expectancy for a baby born in South Korea today is over 80 years!
If the life expectancy for a country is 70 years, that means that some people will die when they are much younger than 70, but many people will live to be older than 70 as well.
Use this phrase to talk about a number which is very high or very low, but which you don't know exactly:
They say it's going to get up to something crazy like 102 degrees this week!
The distance to the nearest star is something crazy like 40 million million miles.
His commute to work used to be something crazy like two and a half hours.
In general, "crazy" can describe something that's surprising:
That is crazy expensive!
I found a crazy number of mistakes in my earlier calculations.
