ELi5 how does your bellybutton and pockets acquire so much lint?
In: 4
The microbes of your skin responsible for keeping it healthy “sweep” bacteria, oil and dead skin cells down there, and of course dust and microfiber (“lint”) from your clothing. As for your pockets, friction from movement between body and clothing against what you keep in them tears off small particles of paper, fabric, et cetera.
