Simply place your fingers onto the sensor pads, then relax while The Oracle reads your vibe…and gauges your stress levels. Are you ''slightly strained'' or ''catatonic?'' Batteries included. Super-chilled or supercharged - which are you? Are you so laid back you are virtually horizontal? A cool customer who never gets hot under the collar? Or are you hurtling towards neurotic meltdown? The Oracle will reveal all.
