Please return your seatbacks and trays to the upright position

Pretty slow at work today. A couple of health tips worth mentioning that I've come across while reading some passenger literature. Amazing what you learn! So, boys and girls, remember for your next flight:

While seated, avoid crossing your legs. (I guess there's no need to be demure in-flight.)

The consumption of alcohol on board should be limited. Because of cabin pressurization, alcohol may have almost double the effect in-flight. (But at least you'd get the most out of that overpriced beverage.)

Passengers should refrain from scuba diving 24 hours prior to departure, and refrain from blood transfusions 72 hours prior to departure. (So forget about that last dive before leaving the Cayman Islands.)

And I can never stress enough, you could be denied entry into a country if your appearance is of a "hippie or transient nature."

Happy travelling.
