Thanks for the response. Which validates I am not
a freak - using UNIX in this CCIE world.
I really doubt I have some psychiatric disorder
after years doing these and isolated no contact
with any family member and the rest of the society.
I have some problem I had been through military draft.
I made an appointment to see a local psychiatrist,
July 19. Will see if I have PTSD.
