Yes, good point, although nail fungus can extremely difficult to get rid of. I've had it on one of my toenails for many years because it got crushed in an injury many years ago. I went through 3 courses of the standard medication, then one course of the extra hardcore stuff that needs to be prescribed by a hospital consultant. It still ended up coming back. These days I keep putting a solution containing tea tree oil on it several times a day, plus I file it down, but it's a very steep uphill battle.
