I do now. I don't run at all anymore, but recently I was crossing the street and a car slowed down to allow me to cross. When the person waived to me, I began to trot across the street--let's just say, my mind said trot but my legs said walk. I almost fell over after taking those first few steps. My upper body leaned forward in running mode and my arms began to swing, but my legs decided to walk instead.
So, what the person waiting for me to cross saw was a rather disturbing walk, where I almost fell on my face because my legs were not cooperating. I put one hand down to catch my fall. I must've looked like I just started walking after years of being bed-ridden. I couldn't lift my feet for that short trot. I had like no bend in my legs, like my knees didn't get the message from my brain. "Jeez, what's that guy doing? It looks like he's trying to tie his shoe and walk at the same time. It's like a Frankenstein trot."
I stick to walking, not running across the street now.
