Something as simple of tonsilitis (sp) will work. The older you are the more they resist taking them out because for some reason for an older person it is a difficult operation. Anyway it would work. One year I got sick with tonsilitis on March 11 and on April 9th I was still sick and still on antibiotics. Also it gave me so much fluid in my ears that I started going deaf. I'm sure I would not have been allowed to fly due to all the problems I was having with ear pressure from it. So this is really a simple solution.

Have M & J in someplace like Australia and have one of them get a terrible ear infection. Which I have also done on vacation twice. Your around those bacterias your system isn't use to.
