I'm also quite the tripper.
I have difficulties walking on grass, on cobbled streets, steps, indoors where there's always different level carpeting/rugs/hard floors,... If there's something to trip on, I'll do it.
You're not alone. Sometimes maybe some of us lack grace, or coordination,....and sometimes it's because there are thick mats or carpets in strange places, or they curl over, and *boom*, down we go!
