    Humans have been aware of the significance of blood for thousands of years.\u00a0 In the time of Aristotle in Ancient Greece approximately 2300 years ago, all body fluids were considered to be a type of “blood,” even tears, urine, and mucus.\u00a0 The names may have changed, but we understand blood is essential to human life, and loss of blood is life-threatening.<\/p>\n<\/div>\n<\/div>\n<\/div> <\/div>\n<\/div>\n <\/div>\n <\/div>\n <\/div>\n

    Many animals, including some humans, have a strong physiological response to the sight, smell, or taste of blood.\u00a0 This would make evolutionary sense, avoiding blood loss could be critical for survival.\u00a0<\/p>\n

    Unfortunately, this makes thinking about blood challenging for many people.\u00a0 We’ll do our best to limit potentially disturbing imagery and topics while introducing this amazing substance.<\/p>\n<\/div>\n<\/div>\n<\/div> <\/div>\n<\/div>\n <\/div>\n
