Yes, I totally agree with that one!!! I've gone a many trips with my dad, most of them being ORD-HNL on the DC-10. I was exhausted after that trip! I'm not saying exercise MUST to be done everyday but whenever the chance presents itself, take advantage. Hell, even 20 minutes of situps, pushups or some other calisthenic in the hotel room will make all the difference! I do plan on writing a book about maintaining health/fitness, just for pilots and flight attendants sometime within the next 5 years. I need to get into my first flying job and experience everything first hand before I begin writing it. Any suggestions, I'm open for it! One thing I would like to address really quick is that long hours of sitting can be, in extreme cases, fatal. If the blood isn't flowing through the legs at a normal rate, it can coagulate, form a clot and possibly end up right in your heart. Your dead before you hit the ground. :-( This happened to a well known U.S. reporter in Iraq who was sitting in a bomb shelter for 9 hours. 9.99999 times out of 10, this will not happen but it's something to consider and be aware of. Drinking only water during your trips will help keep the blood on the thin side and prevent this from happening. Don't let yourself become dehydrated!! Ok, I'm zipping my pie whole now!
