Changing line on a reel

I tend to see in books that they advise to change line every year. I think
with the quality of line produced today it can last much longer. I tend to
replace if I feel the line is an issue, or as mention previouslt to cut off
a 10-20 meter lenght and use line which has not taken so much stick.

just my two pence worth

How frequently should the line on a reel be changed?

For example I have 5lb line that is 4years old and has not been used
in those four years...

thanks.
