Thickle of Joint

I’m aging.  No big deal.  It is part of life: we are born, age, die, then do it again until we attain enlightenment.  I have no doubts of this.  

My joints ache.  

This morning, I surprised the gods and woke up while they were still talking.  Has that ever happen to you?  You wake up and hear that voice that puts you to sleep and tells the stories of your dreams.  

The voice said, “You are thickle of joint.”  

It was an old-English voice this time.  

Anyone know what “Thickle of Joint” means?
