Basic co-ordination, spatial awareness and short-term memory...
I am deficient in all of these. It usually causes minor embarrasments when I bump into the only other person on the pavement in about 10 yards, but occasionally works out much worse.

I am a barmaid. In fact, I am writing this now at the end of the bar instead of soing barmaid-ily duties. This has caused all sorts of incidents, but the worst being about six months ago, when putting some bottles into the fridge, I neglected to look up when standing up. I thought about it, and due to my extreme lack of spatial awareness, I had decided I was at least 2 foot to the right of the till. I wasn't. The till drawer was open. I ripped half my ear off, due to the extreme force I stood up with. It hurt. It needed stitches.

I also have appalling short term memory. This means if something is on the floor, even if I put it there, even if I've been told it's there 30 seconds before I get up, I will trip over it. It is inevitable. The worst culprit for this is the beam in my partner's bedroom. I've been staying there for two and a half years now. I know it's there. I know to duck slightly when I'm standing up. Every time I stand up the boyfriend shouts 'Be careful!' 'I KNOW!!' I scream in earnest... 'DO YOU THINK I'M COMPLETELY STUPID?! I'VE BEEN STAYING HERE FOR OVER TWO YEARS!!! STOP PATRONISING ME!!!' So he promises to not say it any more. And I stand up. And whack my head. This happens at least once a week...

Length? Once a week for 30 months...
