Ghosts have been a stumbling block in the development of a UV complete quantum field theory for gravity. We discuss how difficulties associated with ghosts are overcome in the context of 0+1d QFT. Obtaining a probability interpretation is the key issue. and for this we discuss how an appropriate inner product can be constructed to define a sensible Born rule. https://parisnaturalfoodes.shop/product-category/methyl-folate-1000mcg/
