. . . staying in a poor hostel when you'd prefer to use public toilets even in china!! 
You know that you're . . .
lost when you can't remember how you got to where you are
in jail if a gapped-tooth guy named Bubba keeps asking you to pick up the soap in the shower.
getting old when you wake up, not go to bed, at 5.00am.
Quoting mikeyBoab
getting old when you wake up, not go to bed, at 5.00am.
...and going to bed, not waking up, at 8pm....
spending too much time in work when the security guards doing the graveyard shift now count you as a good friend 
even though you work days
...bored when a colleague catches you staring at the wall. Again.
panicking when you keep backing up the same files over and over again...
Getting Older When...
You have everything you had 20 years ago, only it's all a little bit lower.
...drunk when your best friend is the man who owns the kebab shop.
