Tiger
The tiger possesses a bite force of approximately 1,050 PSI, capable of puncturing steel drums and the egos of safari guides who claimed they'd seen everything. A single swipe can generate enough force to decapitate a water buffalo, though tigers rarely feel the need to show off. The Calcutta Institute of Large Cat Mechanics recorded one specimen dragging a 200-kilogram prey item up a vertical incline, presumably just to prove a point.
Their muscular composition represents 62% fast-twitch fibres, enabling explosive acceleration from standstill to 65 kilometres per hour. One does not negotiate with such specifications.
Love
Love operates through an altogether more insidious power structure. The Oxford Laboratory for Emotional Devastation documented cases where this abstract force convinced rational accountants to purchase motorcycles, sensible teachers to relocate to different continents, and at least one maritime insurance broker to take up interpretive dance.
Neuroimaging studies reveal love activates the same brain regions as cocaine addiction, whilst simultaneously disabling the prefrontal cortex - the bit responsible for recognising terrible ideas. The resulting power is difficult to quantify but has historically toppled empires, dynasties, and strict vegetarian principles when the beloved requests a bacon sandwich.
VERDICT
Whilst love's power over human behaviour remains undeniable, the tiger offers something love cannot: immediate, measurable consequences. One always knows where one stands with 300 kilograms of striped carnivore, usually approximately fifteen metres away and closing. Love's power, though considerable, operates on timescales that allow for second thoughts.
