Things not to do...
...if you are an asthmatic with bad knees.
Don't attempt to climb 1545 meters up Mt. Tai. That's 6,300 steps up the moutain. Since I couldn't breath at that point I took the sky car instead of climbing 1,580 more steps which are just about straight up. I have serious doubts about my walking ability tomorrow. Thank God it's a short day and I only have three classes to teach.
