Why can't I cross my eyes?

Factual Questions
1

I’m the only person I know who can’t cross their eyes? Why? I’ve tried every method anyone has ever told me. Why is this? I’m not really bothered, just curious…

You most likely can (and do) and just don’t realize it (or can’t consciously control it).

Hold out your finger and look at it. Now, bring it as close to your face as you can while still keeping it in focus Congratulations, you’re crossing your eyes!
