The best way to check this was after a working day. Before going to the shower room after the shift, I scooped out a bunch of conventional dust from the navel to the slightest speck of dust. Although not dust, more on that later.
After weighing, our experimental lump showed a weight of 16 milligrams. Next comes school mathematics.
16 milligrams = 0.016 grams
Next. Work is proceeding according to the 3/3 schedule, i.e. half a month. We take into account all 12 months, excluding vacation, although not during working hours there may be a different weight, so an error is allowed. There is a simple calculation left: 0.016 * 15 * 12/1000, we get 0.0028 kilograms of "umbilical dust" and this is with an error of ten thousandths.
P.s. on weekends, "dust" also takes place, no one forgot about it
P.s. in the navel, not only dust accumulates, but also clothing fibers (if you wear a white T-shirt - white dust, if black - black), a slight secretion of sebum, dead skin particles and, directly sweat. But that's a completely different story.
Not at all. In nature, there is no navel in which at least one kilogram of dust will collect. Even if you are notoriously dirty, the account will be kept in grams, nothing more.
With a balanced diet and regular exercise, can you lose 10 kg in 2 months, or does it take longer?
