-You don't really think this stuff scares me, do you?
-Well, fear is a relative thing, I've always found.
What does the second person mean?

The amount of fear depends on the thing that you are afraid of.

It probably also means that the same thing can inspire different amounts of fear in different people. In other words, the amount of fear depends on the person.

Thanks, Clive. I was just hesitating because of the "I've always found" part.
Hi again,

It means 'In my experience', 'this has always been my experience'.

Best wishes, Clive
Thanks again!
