So I hurt my right knee over 5 years ago. It's still there. But it has gotten better. Now, it seems like every time I fall, it's on my right knee. Every time I bang into something, it's my right knee.
So I smashed my bird finger about a month ago. It's still black and blue. Every time, I shake my hands to dry them off from water, I hit my finger. It's always my right hand, and that same bird finger.
My left shoulder feels weird sometimes. As if, like some cosmic physiological energy of pain emanating. Wouldn't you know, every time I bang my shoulder, it's the same left shoulder.

I guess if I'm going to keep injuring myself, might as well keep it all in the same area instead of spreading it all around.
