Getting your nails done when you’re morbidly obese is like painting a house while it burns down.  AKA: "straightening the deck chairs on the Titanic"...  And yes, I feel the pain.  the past 3 times I've gone to any local nail shop to get my hands tidied up (I'm a spastic and can't paint nails straight), the salon was overflowing with the kind of fats you describe.
