I'm occasionally clumsy enough to fall into more or less every scenario that gets brought up this way. Most of the time, however, it scales back to a manageable level of ungainliness. I seem perfectly normal or above average when doing anything I'm familiar with. I rarely have entire days when nothing goes my way in this regard, but when they happen, it's usually because something in my workflow or social life went truly haywire.
