For a long time, the standard for "normal" blood pressure was 120/80. The current thinking is that a more healthy pressure is actually 110/70. 106/64 is a little lower than the norm but may be totally normal for you. If you become dehydrated it can lower your blood pressure and if your blood pressure goes too low it can cause feeling faint or passing out. If it's never been an issue and your MD doesn't have a problem I wouldn't worry.
No, only newborns should use ear tubes, because their ear holes are bigger than people from the ages between 50-65 because by the ages between 50-65 it would be too small for the tube to be able to go in.
