This is very amusing, but I don't think it has much bearing on the main question, that of subjective time. What is the objective duration of a subjective moment, or of a quale? Probably at least 1/20 second. So "you" probably "live" at least that long. Since subjective moments overlap, by extension you live much longer, although incompletely or with variations.
