When things come in a bit too fast we can start sliding out of the healthy balance that our nervous system provides and we start shutting down if we can't catch it in time.
Basic life functions shut down in a specific order. First our gut, then kidneys, then our cardio/circulatory system, respiratory system and then our brain. This can be devastating to the immune system and illness can set in. If a person has had a lot of trauma from birth and the first few years of life, this pattern is usually imprinted right into their nervous system and this is where we often see chronic illness.
These patterns can also be put in motion by ancestral influences. How is that? You might like to watch these short 2 minute videos.
