Hi Emma!  It is likely the age thingee.  I am 67-68 in Dec.  You young chicks get a pass on this.  My window for clearance closed a long time ago.  I'M OK with the additional requirements.  Shows that Dr. Chet. is professional, cautious and thorough in his approach to this life changing  procedure.  I have waited for this for a long, long, time, but life (a wife, 3 teenaged sons & a career) got in my way.  Now, these responsibilities are behind me.  Time to live for me and not everyone else.  None of us know when we will leave this planet,  when I depart, it will be as a woman in all respects.  Thanks for you interest.
Hugz,
Joi
