As others suggested, this is common in sports. I believe the reason is epinephrine release. Epinephrine (also known as adrenaline) greatly improves attention to details and vivid memories by enhancing the brain, facilitating long-term memory recording. From wikipedia: --- Epinephrine acts by binding to a variety of adrenergic receptors [...]. Its actions are to increase peripheral resistance via α1 receptor-dependent vasoconstriction and to increase cardiac output via its binding to β1 receptors. The goal of reducing peripheral circulation is to increase coronary and cerebral perfusion pressures and therefore increase oxygen exchange at the cellular level.[64] While epinephrine does increase aortic, cerebral, and carotid circulation pressure, it lowers carotid blood flow and end-tidal CO2 or ETCO2 levels. It appears that epinephrine may be improving macrocirculation at the expense of the capillary beds where actual perfusion is taking place. --- I would argue that adrenaline can turn seconds in to years, the world suddenly starts going in slow motion, especially when your body is trained by having adrenaline rushes frequently. One of the reasons many newly hired SREs learn many things about their stack quickly over incidents is adrenaline rushes... Of course, in the case of incident response, it might have negative connotations as a recent talk at SRECon by a DO employee showed: nearly 70% of SREs had trouble sleeping because of anxiety after am incident.
