I believe that tripping is more common for folks like me than other people with disabilities. I have severe ataxia, and can trip over just about anything.
Tripping is when a person stumbles over an unseen or unexpected floor or surface anomaly. Such anomalies as:
> cracks in sidewalks, or roads
> train or streetcar tracks
> uneven ground such as parks and beaches
> stairs, the smaller the better
> walking from darkness to lighted areas
> things found underfoot that should not be underfoot (disgarded shoes for example)
For me, I can trip over all of those, but also some others that may astound you:
> benches, chairs and other things you may sit on
> children underfoot (I once nearly squashed my youngest son when he darts in front of me)
> walking 0ne way, then suddenly switching directions
> ramps in sidewalks for driveways or crosswalks
> almost anything sticking out of the ground, trees, shrubs, poles, etc
> those yellow wet floor signs you see everywhere, I trip over them because they are usually small and out of my sight range
> toys! My children have too much LEGO strewn all over our basement
> small animals that dart underfoot…
> random feet!
Because I have low vision, I find it very hard to judge distances, or heck, objects from my six feet height to, say, the ground.
I once walked right smack into a pole, that I did not see until I walked into it! I was having this internal conversation after cracking my head: “…what the hell is that pole doing there! Crap! The pain! That lady thinks I’m drunk! Must preserve a scene of normalcy!” I turn to and enter the mall, being swallowed by thousands of people while avoiding judgement by a haughty old woman!
