Take a moment to appreciate the people who have the following jobs. I am merely point out the jobs that most fainthearted people like me, would not be able to do. We rarely think about how good we have it, but without these amazing individuals, our world will be less pleasant.
Surgeons

If you are uncomfortable seeing blood, then this job is out! You wouldn’t want to pass out while opening people up. Surgeons deal with a whole lot of blood all day long to save people.
Meat Cutters

These people are the ones that bring meat to our dinner table. The job they do we can barely imagine leave alone doing the actual chores. I enjoy an occasional steak, but the process of how the meat got into my hands, skipped my mind totally.
During deer season in Michigan Upper Peninsula, I often saw deer hung upside down, and felt very queasy as I drove pass the site.
Undertakers/Morticians

My mind usually takes me on a wild ride when it comes to the funeral home. I’m not afraid of death, but I am just a bit wary around dead body. I would not be able to handle a dead body or do the job of a mortician.
Medical Examiners

Autopsy report requires medical examiner, and this job involves an extensive hand on with the deceased. Unlike surgical doctors who deal with live patient, medical examiners deal with cold dead body. They both perform the same task of cutting, opening the body, but their purpose is totally different.
Blood Specialists

The blood specialists must handle bags of blood. They make sure the blood is safe and the type of blood is correct. They help saves lives, and without these people what will we do?
These are the jobs that constantly dealing with blood. If you are a fainthearted, you can’t be in this business. I am sure there are other jobs that work with blood also, but these are on the top of my list.
