“The shower alone has a panel with more than a hundred options you can choose regulating water temperature, pressure, soaps, shampoos, scents, oils, and massaging sponges. When you step out on a mat, heaters come on that blow-dry your body. Instead of struggling with the knots in my wet hair, I merely place my hand on a box that sends a current through my scalp, untangling, parting, and drying my hair almost instantly. It floats down around my shoulders in a glossy curtain.”
