I was back in Chen Zi Han's room, the place that I was now affectionately calling my cave, trying to figure out the numbers of everything that I needed. At the very minimum, I was hoping to gather enough supplies to last us all for a year, but ideally, it should be enough for the next 5 to 10 years. And let's face it, that was a lot of stuff.
But it was not the sheer quantities that was giving me the headache, but the math. For example; ideally, a single person needs six tubes of toothpaste per year and four toothbrushes. That means for the 310 people currently living here, I would need them to gather 1,860 tubes of toothpaste and 1,240 toothbrushes… for a single year. And don't forget, no one would be producing these things either in the future so it's not like we can go out and get more when we run out.
