Trip Hazards
Clarifications about some vacation hazards from Wall Street Journal (Weekend Journal for March 31 - April 2)
The air on a plane is full of germs
"... but is a plane really any more dangerous than an office, say, or an elevator? Half the air on a plane is outside air, and half is filtered and recirculated. So it would seem as though 50% of your onboard oxygen intake consists of other people's germy exhalations. But the recirculated half passes through high-efficiency particulate air filters, which typically catch almost all dangerous microbes... A well-maintained aircraft has about 20 air changes per hour; that airflow is roughly the same as that in a hospital operating theatre... a typical office building only has about five air changes per hour. It isn't the air on a plane that is the problem... The risk is other passengers who might be close to you for long periods of time..."
Conclusion: stay away from office - it is 4 times germier than a plane
Your room key has your credit card information on it
"... director of corporate security for Shangri-la Hotels & Resorts says it's only a card for access to a hotel room, with just the room number and dates of stay encoded on it... the process of coding a key card - when check-in staff code a key card for a guest, the hotel's key software system allows them to input a room number, check-in and check-out dates and times, and possibly a guest's name... its key coding software doesn't allow hotel employees to put credit card information on a card... hotels have their own individual software for encoding cards. You can't insert a card from Hotel A into a reader from Hotel B and get any readable information from it."
Conclusion: no matter what, nobody should take care of your personal information more than yourself should.
