What is jet lag and why do you get it?

AT first we thought it was just a case of bad jet lag.

But how bad was my jet lag on the return trip?

Once I had children, jet lag became more of a concern.

Sleep, after all, is the best defense against jet lag.

However, most people may be able to deal with jet lag more easily.

They said hitting the ground running was the best way to deal with jet lag.

The symptoms of jet lag may take from one to several days to go away.

Only one hour of jet lag from London, easily written off.

Q: So you really never have jet lag away from home?
