#3 – Dirt Under Nails
Nails. They really are a wonderful place for all kinds of dirt and germs to get stuck and breed under. And we love to sit down and have a poke about underneath them with anything sharp and pointy enough to fit under them, scraping the gunk and grit out. And if you’re at a loss for a suitable implement, you can always use your teeth. Although that might prove a little difficult when it comes to your toenails!
