Here's a stumper for all you RPG fans: exactly how much does taking one hit point of damage hurt?

It's not a particularly straightforward thing to work out, given that hit points are a representative abstraction of physical condition rather than a measurable, uh, measurement. But let's assume for a moment that it is indeed possible to measure one's own hit points. How much, then, would taking one hit point of damage hurt?

The answer to that question would largely depend on what model of hit points you are using. If you're talking Dungeons and Dragons hit points, taking one damage would fucking hurt if you're not in tip-top physical condition. The average "man in the street" sort of person (i.e. not a warrior, rogue, wizard, cleric or what have you) is regarded as a "level 0 human" and generally has something in the region of 2 or 3 hit points, if that. Level 1 wizards often only have in the region of 4 or so. As such, taking one hit point of damage as an average person following the Dungeons and Dragons model would hurt a great deal, putting you potentially up to halfway towards death (or rather, being knocked out, since people don't officially die until bleeding out to -10 hit points in D&D).

Compare and contrast with the JRPG approach to hit points, however, where totals frequently extend into the thousands and, in some cases, the tens of thousands. As a beginning character in a JRPG, you'll often have a low three-figure hit point total to start with, which will progress towards that elusive 9999 (or 99999) as you level up. Assuming that your average person hasn't really levelled up a great deal thanks to a notable lack of monsters (big spiders battled with Hoovers notwithstanding) we can work on the assumption that a single hit point's worth of damage doesn't really hurt a great deal. 'Tis but a scratch and all that.

So, since it's late and my brain is starting to shut down a little bit, let's take this to the next logical extension and consider a variety of horrific injuries to determine exactly how many HP damage they'd do following the two approaches outlined above. We're assuming that the person being injured here is not a Destiny-chosen hero who has been infused by the power of the Goddess/branded by the fal'Cie/chosen by Fate/revealed to be the wielder of the legendary blade Monado but rather, say, that man who works behind the fish counter in Sainsbury's. As such, we'll say he has 4HP in D&D and 150HP in a JRPG.

• Suffering any sort of trauma to the testicular area — D&D: 2HP (probably won't kill you unless you've just been punched twice by a drunk dude at a bar who thought you were eyeing up his missus, but it bloody hurts), stunned for 5 turns, temporary reduction to Constitution; JRPG: 50HP physical damage, afflicted with "Stop" status as you wheeze and cough in an attempt to recover your dignity.

• Standing in the epicentre of a nuclear explosion — D&D: 999HP; JRPG: 9999HP.

Should you find yourself suffering any of these injuries, though, fear not; for a good night's sleep cures all ills, as everyone knows. Unless you're already dead, in which case you'd better get on good terms with your local Cleric or purchase some Phoenix Down.
