Tony is non-plussed by Jet Lag.

On Monday and Tuesday, Tony and his parents spent about 14 hours on planes to get from Canada to China.

And now, unlike his parents who want to get back to a regular sleep schedule and so are grumpy about it, Tony does seem at all perturbed by Jet Lag.  He has gotten up at four a.m., on Wednesday and Thursday, happily playing with his toys or jumping on his parents who are trying to sleep.
