About that first paragraph, I usually was going to buy something anyway, but I want to buy it after I've used the bathroom, because who would want to carry their drink or whatever into a public bathroom?
Contemplating death from old age does activate fleeing behavior, though (at least in me), which is another of those silly bugs in the human brain. If I found a way to fix it to activate cryonics-buying behavior instead, I would probably have found a way to afford life insurance by now.
I can forgive that, since cats express fairly complicated emotions with their body language which are probably beyond the current capability of miniaturized brain scanners. It seems, and I didn't bother to translate any of the Japanese website or anything, like that thing just measures general electrical activity levels.
The scene in question.
