Is it possible for a person in a normal condition to swallow his/her own tongue?

I just watched this period drama which a person loyal to his masters caught and tortured to talk about what he knew. He was to be interrogated when they found out he committed suicide by swallowing his own tongue.

I kept on thinking if that is possible. I tried to swallow my tongue by curling it up putting it’s end near my tonsils. I can feel it seem possible since I choke and makes me vomit that me afraid to try harder swallowing it. I have not done a research yet if it’s possible before writing this one. I will do it later since I already started writing and I feel lazy now to visit Google.

Well, I will just ask you my friends? Without doing a research, do you think it’s possible to swallow your tongue to commit a suicide?
