Actually Henry, further research has revealed that FIR does not affect will power, but gazing at pictures of past GCs that belong to other forum members does, and it also increases testosterone levels significantly, leading to more ballsy purchases (higher dollar). Just go to japankoi and you can graph the obvious spikes in testosterone inspired bidding.
FIR research has revealed that it increases reproductive organ activity, leading to less pond time, reduced stress, and larger average koi size purchases. It also leads to happier pond owner wives, which in turns reduces the jealousy/anger response to expensive koi purchases.
Note- none of this is anything more than fantasy and fiction on my part, not to be confused with the obvious effects of posting pics of GCs, or the obvious effects of FIR on the brain and pond biology.
