If I use an elevator, I feel off-balanced when I get off of it. (only on the trip up- down is fine)
If I stand in one place for too long, I start to fall over.
If I walk on the edge of a sidewalk and start to look where I am about to step, I trip off of the sidewalk.
When I become consumed by an obsessive thought while walking, I either lose my balance or start going in circles.
O__o Wow, I have never listed those issues before. I must be quite amusing to watch.
