[Sbb1413]

My real name is Soumyabrata Bhattacharjee. However, when I heard that the N-1 rocket was cancelled in 1974, that year is always evolving around me. When I was registering on Reddit, I accidentally wrote soumya-8974 instead of soumya-1974 in the username. And then, I am always using that username (soumya-8974).

English lesson: the past tense of set is set.
I can't fathom what the acronym FIYAA means. Did you mean fire?
