I believe I was "selected" just before birth, was monitored throughout my childhood and was visited when I finally made the connection -and call- as a young man.
When I began questioning my ET-history at a young age, I went to the public library and in their microfiched nespaper records [Yeah: it was THAT long ago!] I found that on the night and time of my birth a UFO wa tracked across three states before disappearing just south of my hometown. MY Mom ocnfirmed later that when I was born I wasn't expected to live - that the Drs. were amazed that I rallied so quickly.
I should also mention that I've always known I was being watched and saw my first UFO at the age of 9 [there was one other witness with me] but have never felt any fear from that observation.
As a pre-teen I developed a strong interest in ancient cultures and have studied them ever since, in particular those of Egypt and Rome. Later, When other 14 yr olds were devouring MAD Magazine I was reading Plato, Aristotle, Cicero, etc. and absorbing them like a sponge... they al seemed to be old, familiar friends! I still read them, and today have a modest collection of artifacts from both of those historic periods. In fact, as I write this I'm wearing a Bronze ring that was originally crafted for a foot soldier in Rome's XX'th Legion.
Shortly after I put out "the call" visitations [I refuse to call them abductions] occurred on a fairly regular basis [every 3-4 months] and I was able to summon them if I felt the need. Shortly after that routine started, I noticed someting new: an impant at the base of my skull; I was told by my "watchful ones" that it was a life-recorder that they downloaded during their visits. At the same time I was given a physical check [via probing which always hurt like Hell] where they would correct any health issues I had. I should mention at this point that today I am 67 years old and in excellent health... I've never even had a personal phsyician! I've never needed one. I take no medications or special care of my body, including nutrition: I eat like a teenager and still manage to thrive on such stupidity!
Some of my latent senses have also been awakened from the experience. I am a telepath, and am a much better "sender" than 'receiver", but can travel in OBE's pretty easily.
I carried that implant for eight years until I finally asked them to remove it - and they did with no hassles. But, since that day the visits ceased and I've had trouble contacting them.
