Yet children without skin to skin contact can die. Infant mortality in orphanages is very high..this is well documented. This belief is not! There are a myriad of reasona why humans do this. Interestingly, cats also do this. you can believe this if you like but the only science that supports this is... well nothing. Only well wishers and people hoping to find trascendence in meaningless ideas posing as enlightenment. Man is spirit and is created in the image of God. Any act of love between two people sharing concern and mutual participation in the troubles of life translate to love. Not hard.
