<unk>  is a display of extreme physical<unk>  by humans, beyond what is believed to be normal, usually occurring when people are in life-and-death situations. The classic anecdotal example is parents lifting vehicles to rescue their trapped children. The extra<unk>  is commonly attributed to increased adrenaline production. Research into the phenomenon is difficult, though it may be possible as adrenaline is known to affect muscle twitch and endurance. Norepinephrine is pointed as a more compelling cause of this phenomenon. Unexpected<unk>  is claimed to occur during excited delirium.
