If I can choose which cells to convert this is really fantastic. I shed millions of cells every day naturally, I'd pick the epithelial cells I'm about to lose anyway. A pint of blood has 2 billion cells and blood donation is generally limited to one pint every 56 days, so that's ten million dollars a month from spare blood cells alone. Skin sheds a million cells per day, that's a nice ten thousand dollars a day for doing nothing and it will reduce house dust buildup in the process.

And if I ever got cancer, ka-ching!
