Skip the Jump

I'm reading Packing for Mars, and in the entire chapter devoted to ralphing the author has this handy tip.  When trapped in a plummeting elevator, lie down.  That goofy business about jumping in the air just before you land is not useful.  Because you are going to hit the floor.  According to author Mary Roach, who researched the heck out of this book, the body is best engineered to handle pressure in the supine position. NASA knows this due to years of studying the effect of buckets 'o gravity on humans.  One of the many offshoots of NASA research that can be applied to everyday life, ladies and gentlemen!  Bonus fact:  some motion sickness is caused by calcium deposits in your inner ear.  They're supposed to be there, but don't like it when you move your head too quickly.  I always thought of calcium as being more relaxed.
