Could a person have never vomited throughout his life?

Could be. As an example, I can nominate myself. I have never did it in my life. Sometimes I even said to myself, "Am I a stomachless, disgusting person?" I asked. But then I thought it was a good thing.

I can not use it if I want to. Of course there is a plus. For example, I am not messing around because it is on the road, or when I feel dizzy. When I drink too much alcohol, I do not. But of course there are also negative aspects. I have no chance to relax, which is the most common. In the case of nausea or abdominal pain, I have no chance to finger and relax. I have tried many times but I could not succeed. More importantly, when you notice any poisoning situation, you can immediately snap your finger and save your life. Let's say you realized you ate poison somewhere. You can return from death by vomiting, but I have to wait for the ambulance.
