In the past, she has stated that she spent 10 years as an EMT with the Mexican Red Cross in the Tijuana area. She has said that she received training as a fireman while she was an EMT. She has also implied that she served with the IDF at one point, but I don't think she has given any details.
Could be, could be she is short but so is DR .Ruth at 4' 11" and she served in the Israeli Army.
In her book she tells of at 12-13 being taught to while blindfolded to take apart and put back together a machinegun of some kind. Those people do not fool around.
When Mother came home from a tour of Israel 8 or so years ago she told me of seeing children smaller then herself on the streets fully armed. Mother is 5' tall and weighed 90 pounds at the time.
From what I gather everyone is drafted for defense and unless in a coma the Government will find a job for you to do.
So Nad's may have when she was younger and thinner and stronger may have volunteered for some jobs that did not require her to do the job of a man or woman twice her size.
Much like her "JOB" today she may have thought of volunteering as a JOB and may indeed seen some action as she did clean up work on something or other.--+
I am trying to understand Nad's and it is no easier then she trying to understand me.
