Another thing to try and remember. I am now 12.459 metric kilodays old. Let's see, there are 2.74 standard years in a metric kiloday. That makes me 34.14 years, more or less. How much is that in nanoseconds?
With my metric cloth measuring tape I have a 61 cm waist which converts to about 24 inches. I don't know, 61 makes me sound fatter than 24!
I'm afraid if we give this idea 25.4 mm it will take 1610 meters.
