Will we scold in the past? We are not satisfied only with the personal, but also with the large scale, imagining: oh, if not for this, oh, if not for this? "Oh, if only" - you did not exist - may be similar (and the larger the "microshift" with a fraction of a second, the less similar), but a different personality is not a static fact, but a dynamic result of a unique set of circumstances. It all starts at the level of reproductive mathematics: at the moment of conception, millions of spermatozoa compete, each of which carries a unique combination of genes after transition. A change in the parent's breathing or the slightest delay for a split second completely changes the winner. At that very moment, the biological probability of a certain person is erased, and instead his genetic brother or sister is born with a fundamentally different temperament. Even the physical body is perfect in accidents. Fingerprints and unique retinal patterns are not encoded directly in DNA; They are formed during intrauterine development under the influence of chaotic microturbulence and amniotic fluid pressure. Every movement of the mother or second change in her biochemistry creates a different pattern of skin and capillaries. That chaos creates the physical architecture of memory and the connectome - a map of billions of neural connections. Memories and worldviews are not stored in the brain as files on a disk. These are material assemblies of neurons held together by synaptic plasticity. The brain is constantly performing synaptic pruning - severing some connections and strengthening others based on momentary experience. Every micro-change in the past triggers a restructuring of this architecture. The brain physically becomes different. Epigenetics works in parallel: external events place chemical marks on the DNA, turning certain genes on or off. The slightest change in environmental conditions in the past changes these signs, changes the hormonal background and the sensitivity of the receptors for dopamine, serotonin or cortisol.
