Anesthesia improves health and longevity by making many surgeries possible and easier. Open heart surgery, and many more like this, would not be possible without anesthesia, so the people who has a heart defect would be left to die. It makes other surgeries like amputations and oral surgeries easier, so the patient does not have to go through the pain. Without anesthesia patients have to suffer through the agonizing pain of surgery or labor, and can die from it. Anesthesia is a more effective and safer way to make people unconscious in comparison to alcohol which was the only other effective but dangerous option. Since anesthesia opens up the availability and improves surgery, health problems that can not be healed on its own, can be treated
