Our life vs. Our lives

[englishteacher79]

I know I don't have a context, but I've always wondered whether we should say "our life" or "our lives" and if both are possible, what are the rules to this?

Thanks.

A: How is vacation?

B: Wonderful! I'm having the time of my life!
B: Wonderful! We are having the time of our lives!

Instead of saying "I know I don't have a context", you could have come up with a couple of sentences of your own to demonstrate your question.
