You know when you get up in the morning, and you're still stiff and inflexible and kind of fall down on your way to the kitchen?
Or when you've been sitting for a while and then get up to walk and can't do it without looking like a weird alien trying to blend in with humans?
Or when somebody reccomends that you do some stretches before you go for a run, and you remember that you haven't been able to literally touch your toes since you were seven?
