Most of the comments in this thread are ridiculous.

Just as you (hopefully) get to choose how many hours you work, your coworkers also get to choose how many hours they work.

I'd ask yourself two questions:

1: Are you happy with your current work/life balance?

2: Can you achieve your career goals at your current workplace while maintaining your desired work/life balance?

If the answer to either of those questions is "no", you should have a conversation with your manager.
