you are fat, not buffed so no its not possible
have you ever fought irl?
i remember when i got punched in face by friend who trains kickbox for years and i wasnt KO'ed (he's buffed) and i wanst KO'ed ( i had 14 years) why should someone whos old get knocked out by some fatso so easily??
Also, you cant knock someone when you hit him in face, cause you dont hit him near his brain, only the hitting (not punching) in backhead can have an effect.
