So who has a 'Superpower' - some weird thing you can do that others can't.

After reading the discussion on synesthesia, I thought it would be nice to find out what other weird, interesting or even useless ability we all might have.

I have an almost Jack Reacher like clock ability in my head. If I set the alarm for the morning, I will always wake up a few minutes before it goes off - I am NEVER awakened by the alarm no mater how tired I was when I went to bed.
