Okay I dislike Biden just as much as the next guy, but I’m giving him a pass on this one. I walk like that too now. I’m not on Thorazine, I’ve got bad knees. My right knee especially goes out without warning a lot, so I walk kind of stilted like that instead of striding out like I used to.
Get both knees with bone-on-bone contact pain and you’re not going to ‘stride’ anywhere.
I bet you don’t walk with that immobile head dead expression.
If you do then perhaps you should pay more attention to how people look at you and talk to you.
