My daughter was looking to adopt a child , her and hubby went through rigorous tests and courses during this time they were told that babies have something called cellular memory and should any trauma happen to the child from the moment of birth it is retained in the memory cells . Therefore they were advised a child could have life difficulties or problems due to this cellular memory .

It seems that trauma does affect us even from birth and in later life it can come to the surface .

So it would seem that certain memory's can stay hidden through life then just open up later on

So he should be. No doubt he was practicing his skills whilst in his mothers womb.
