The record shows that you believe a lot of things that are nonsense, this 
one making no exception.

It is nonsense because if it were true, atoms would not exist, and you, 
being built from atoms, would not exist.  For it is well-known (i.e. 
experimentally confirmed countless times) that matter and anti-matter 
annihilate each other.

A common application of that knowledge is Positron Emission Tomography in 
medicine, where the positrons (anti-electrons) emitted by atomic nuclei of a 
radioactive isotope (like fluorine-18) brought into the patient’s body 
annihilate (by swallowing it or by injection) with the electrons of the 
atoms of the patient’s body, producing (at least) pairs of photons which can 
be detected:

  e⁻ + e⁺ → γ + γ (+ …)

So you should sincerely hope that the atoms of your body are not “half 
matter and half antimatter” the next time you need a PET scan.
